So, I have noticed that when people are crowded in small rooms, it feels hot. In fact, everyone in the crowd feels hot and starts sweating. I am wondering about the origin of all this heat.
I do know that by first law of thermodynamics, if two people touch each other and if one of them feels the other is hot, the other person has to feel that that person is cold.
The problem is if all the people in crowded places feel hot, then heat must be generated by themselves or the air (with respired CO2) around them must be hot (in which case, crowded open places should not feel hot, which I'm not sure about).
It cannot be the feeling of heat by some other person, because if that is so, the other person should feel cold by that person.
