I am seeing a trend that I quite like after going through this page and the last page of this thread. Someone asks for advice on how would they write a certain theme say violence or food and thereafter follows the responses!
I need help with thermodynamics. Can someone tell me the difference between heat energy and internal energy? Can 'hotness' and 'coldness' be measured scientifically (I think the answer is no)? Can someone write a story out of it?
You do know that that's what temperature scales are for right? To measure heat? And there is no way to measure cold. It's just the absence of heat so another way of saying, "It's damned cold out here!" is, "There's, like, no damn heat out here!" Doesn't quite have the same ring to it.
Not really. Temperature scales are used to measure internal energy not heat itself. (Temperature difference is used to measure heat energy. I will go into detail later) Higher the internal energy, higher the temperature. Internal energy is the energy from the vibration of (atomic / molecular) particles within an object.
Heat or cold are just sensations. So what I am arguing here is that it makes little sense measuring heat or cold.
If you are talking about heat energy, then it only comes about when there is a temperature difference between two objects (the word for it seems to be 'systems'). Heat energy if I am not mistaken if the energy that goes from an object that has higher internal energy to one that has lower internal energy.
I wanted someone with knowledge of thermodynamics to corroborate with what I have learnt about that subject. Wherever possible, I try to mix as much reality as possible into what I write, fictitious as it may be. Wanted to do the same for the competition.
d: I was half-joking. I was not clear but I wanted to see if someone can write a passage centred around thermodynamics just for laughs. However, I do really want to ascertain a few things pertaining to thermodynamics.
