Thermodynamics

Question 1

0th law of thermodynamics

Answer 1

law about thermal equilibrium

If object a is in thermal equilibrium with object b and object b is in equilibrium with object c THEN object a and object c are in thermal equilibrium too

Question 2

What phase change results in the greatest increase of entropy?

Answer 2

Sublimation (solid to gas)

Question 3

True or false: entropy increases from gas to liquid to solid

Answer 3

False: entropy decreases with increasing order of molecules (solid= most ordered)

Question 4

What is an isolated system?

Answer 4

A system that cannot exchange energy (heat and work) or matter with its surroundings (ΔU=0)
