Is 熵 in any way part of the spoken language? In my own language (Dutch) I can (jokingly) point at something that is decaying (or perhaps my tea getting cold, or my desk being disorderly) and utter the single word: ‘entropy’. Or I can, out of the blue, say (again, jokingly): ‘I hate entropy’.  

Considering that ‘entropy’ is simply  shāng in Chinese, which, apart from  熵, can also be 商, 傷 or 墒, is either of these statements  that I can make in Dutch, also possible in the Chinese spoken language (without being unintelligible)? (Pointing and saying shāng, or perhaps wǒ tǎoyàn shāng.) If not, would there be a work-around that still involves the concept of entropy, or is 熵  restricted to a physics class and/or the written language?
As a Chinese, I saw 熵 only in my Chemistry class. Don't use that in your daily life, or people get confused by what you say. If you are talking with a people with low education, he or she won't even know this word.
