question: Why is it when you first get in a shower the water can feel really warm when you put your body in it but feel really cold if it splatters on you?
comment: The water cools very quickly as it comes out of the shower head. To test this notice how nice and warm it is standing very close to the shower head and then sit or squat far away from it. You've moved yourself only a couple feet further away but the water will be noticeably colder. The smaller the volume of water the faster it cools in air. Tiny drops that splatter onto you cool the moment they leave the pipe and the rest of that water.
passages: These splash pools are often isolated from the moderating influence of the ocean and therefore the pools can vary dramatically in environmental factors such as salinity and temperature over the course of hours or days. "T. californicus" has the ability to thrive under these variable environmental conditions (factors that limit predators such as fish to lower pools in the intertidal zone). Temperature in the pools that this copepod inhabits tend to track air temperatures more closely than ocean temperatures and salinities in pools can change as pools evaporate, receive freshwater inputs from rain, or saltwater from wave actions.
   The “radiation effect” results from radiation heat exchange between human bodies and surrounding surfaces, such as walls and ceilings. It may lead to phenomena such as houses feeling cooler in the winter and warmer in the summer at the same temperature. For example, in a room in which air temperature is maintained at 22° Celsius at all times, but in which the inner surfaces of the house is estimated to be an average temperature of 10° Celsius in the winter or 25° Celsius in the summer, heat transfer from the surfaces to the individual will occur, resulting in a difference in the perceived temperature.
   Research has tested the model against experimental data and found it tends to overestimate skin temperature and underestimate skin wettedness. Fountain and Huizenga (1997) developed a thermal sensation prediction tool that computes SET.

   Skin wettedness is defined as "the proportion of the total skin surface area of the body covered with sweat."

  While air movement can be pleasant and provide comfort in some circumstances, it is sometimes unwanted and causes discomfort. This unwanted air movement is called "draft" and is most prevalent when the thermal sensation of the whole body is cool. People are most likely to feel a draft on uncovered body parts such as their head, neck, shoulders, ankles, feet, and legs, but the sensation also depends on the air speed, air temperature, activity, and clothing.
  
  Section::::Models.:PMV/PPD method.:Local thermal discomfort.:Vertical air temperature difference.
   The wetness of skin in different areas also affects perceived thermal comfort. Humidity can increase wetness on different areas of the body, leading to a perception of discomfort. This is usually localized in different parts of the body, and local thermal comfort limits for skin wettedness differ by locations of the body. The extremities are much more sensitive to thermal discomfort from wetness than the trunk of the body. Although local thermal discomfort can be caused from wetness, the thermal comfort of the whole body will not be affected by the wetness of certain parts.
   If, for example, someone flushes a toilet while the shower is in use, the fixture suddenly draws a significant amount of cold water from the common supply line, causing a pressure drop. In the absence of a compensating mechanism, the relatively higher pressure in the hot water supply line will cause the shower temperature to rise just as suddenly, possibly reaching an uncomfortable or even dangerous level. Conversely, if someone opens a hot water faucet elsewhere, the relatively higher pressure in the cold water supply line will cause the shower temperature to drop suddenly.
   We can observe and compare the rate of radiation heat transfer between a person and the surrounding surfaces if we first make a few simplifying assumptions: 
  
  BULLET::::- The heat exchange in the environment is in a “steady state”, meaning that there is a constant flow of heat either into or out of the house.
  
  BULLET::::- The person is completely surrounded by the interior surfaces of the room.
  
  BULLET::::- Heat transfer by convection is not considered.
  
  BULLET::::- The walls, ceiling, and floor are all at the same temperature.
   Although thermal pollution is subject to regulation under the CWA, definitional questions have resulted in litigation, including whether even water itself may qualify as a "pollutant" (e.g., adding warm water to a stream). The United States Supreme Court addressed these issues in "Los Angeles County Flood Control District v. Natural Resources Defense Council, Inc." (2013).

   It was using this explanation that academic philosophers claimed that cold, on many occasions, increases a body's temperature, and dryness increases its moisture. Thus, it was said, quicklime (CaO) was apparently set ablaze when doused with cold water (an effect later explained as an exothermic reaction). It was also the understood reason for why water, such as that in wells, appeared warmer in winter than in summer (later explained as an example of sensory adaptation). It was also suggested that thunder and lightning were the results of antiperistasis caused by the coldness of the sky.
   Many illusions in vision are caused by adaptation, the prolonged exposure to a previous stimulus. In such cases, the perception of a subsequent stimulus is altered. This phenomenon is sometimes referred to as a contingent after-effect. Similarly, adaptation can cause such illusions in the sense of touch.
  
  BULLET::::- If one hand is immersed in cold water and the other in hot for a minute or so, and then both hands are placed in lukewarm water, the lukewarm water will feel hot to the hand previously immersed in cold water, and cold to the hand previously immersed in hot water.
   The radiant temperature is related to the amount of radiant heat transferred from a surface, and it depends on the material's ability to absorb or emit heat, or its emissivity. The mean radiant temperature depends on the temperatures and emissivities of the surrounding surfaces as well as the view factor, or the amount of the surface that is “seen” by the object. So the mean radiant temperature experienced by a person in a room with the sunlight streaming in varies based on how much of his/her body is in the sun.

   In humans, the diving reflex is not induced when limbs are introduced to cold water. Mild bradycardia is caused by subjects holding their breath without submerging the face in water. When breathing with the face submerged, the diving response increases proportionally to decreasing water temperature. However, the greatest bradycardia effect is induced when the subject is holding his breath with his face wetted. Apnea with nostril and facial cooling are triggers of this reflex.
   When two solid bodies come in contact, such as A and B in Figure 1, heat flows from the hotter body to the colder body. From experience, the temperature profile along the two bodies varies, approximately, as shown in the figure. A temperature drop is observed at the interface between the two surfaces in contact. This phenomenon is said to be a result of a "thermal contact resistance" existing between the contacting surfaces. Thermal contact resistance is defined as the ratio between this temperature drop and the average heat flow across the interface.
   The film was the directorial debut of Kasdan, screenwriter of "The Empire Strikes Back" and "Raiders of the Lost Ark".
  
  Section::::Plot.
   BULLET::::- "Thermal conductivity": The container of hotter liquid may melt through a layer of frost that is acting as an insulator under the container (frost is an insulator, as mentioned above), allowing the container to come into direct contact with a much colder lower layer that the frost formed on (ice, refrigeration coils, etc.) The container now rests on a much colder surface (or one better at removing heat, such as refrigeration coils) than the originally colder water, and so cools far faster from this point on.
   When the two bodies come in contact, surface deformation may occur on both bodies. This deformation may either be plastic or elastic, depending on the material properties and the contact pressure. When a surface undergoes plastic deformation, contact resistance is lowered, since the deformation causes the actual contact area to increase

  The presence of dust particles, acids, etc., can also influence the contact conductance.

   Scalding is a serious concern with any water heater. Human skin burns quickly at high temperature, in less than 5 seconds at , but much slower at — it takes a full minute for a second degree burn. Older people and children often receive serious scalds due to disabilities or slow reaction times. In the United States and elsewhere it is common practice to put a tempering valve on the outlet of the water heater. The result of mixing hot and cold water via a tempering valve is referred to as "tempered water".
   Section::::Thermal stress.
   Heat transfers very well into water, and body heat is therefore lost extremely quickly in water compared to air, even in merely 'cool' swimming waters around 70F (~20C). A water temperature of can lead to death in as little as one hour, and water temperatures hovering at freezing can lead to death in as little as 15 minutes. This is because cold water can have other lethal effects on the body, so hypothermia is not usually a reason for drowning or the clinical cause of death for those who drown in cold water.
   According to the laws of thermodynamics, all particles of matter are in constant random motion as long as the temperature is above absolute zero. Thus the molecules and atoms which make up the human body are vibrating, colliding, and moving. This motion can be detected as temperature; higher temperatures, which represent greater kinetic energy in the particles, feel warm to humans who sense the thermal energy transferring from the object being touched to their nerves. Similarly, when lower temperature objects are touched, the senses perceive the transfer of heat away from the body as feeling cold.

  Referring to conduction, Partington writes: "If a hot body is brought in conducting contact with a cold body, the temperature of the hot body falls and that of the cold body rises, and it is said that a "quantity of heat" has passed from the hot body to the cold body."
  
  Referring to radiation, Maxwell writes: "In Radiation, the hotter body loses heat, and the colder body receives heat by means of a process occurring in some intervening medium which does not itself thereby become hot."
