Thermodynamics is the study of how particles react and how energy works in a system. There are four facts that hold true in every thermodynamics situation:

If two systems are in thermal equilibrium with a third system, then they are in thermal equilibrium with each other.

- Heat and work are forms of energy transfer.

Entropy in a system not in thermal equilibrium increases.

- Entropy in a system approaches a constant as temperature approaches zero.

These ideas are most likely called

O a thermodynamics experiment.

O a thermodynamics hypothesis.

a theory of thermodynamics.

“dear sir: it is with great reluctance, i trouble you on a subject, which does not fall within your province; but it is a subject that occasions me more distress, than i have felt, since the commencement of the war; and which loudly demands the most zealous exertions of every person of weight and authority, who is interested in the success of our affairs. i mean the present dreadful situation of the army for want of provisions, and the miserable prospects before us, with respect to futurity. it is more alarming than you will probably conceive, for, to form a just idea, it were necessary to be on the spot. for some days past, there has been little less, than a famine in camp. a part of the army has been a week, without any kind of flesh, and the rest for three or four days. naked and starving as they are, we cannot enough admire the incomparable patience and fidelity of the soldiery, that they have not been ere this excited by their sufferings, to a general mutiny or dispersion. strong symptoms, however, discontent have appeared in particular instances; and nothing but the most acitive efforts every where can long avert so shocking a catastrophe.” what’s the central idea?
