What is the formula for pressure-volume work?
What is the formula for pressure-volume work?
- w = p / ΔV
- w = -p * ΔV (correct)
- w = ΔV / p
- w = p * ΔV
What happens to the internal energy of a system when it gives off heat or does work?
What happens to the internal energy of a system when it gives off heat or does work?
- It increases
- It remains constant
- It decreases (correct)
- It becomes zero
What is the relationship between the change in internal energy of a system and its surroundings?
What is the relationship between the change in internal energy of a system and its surroundings?
- ΔU_system = ΔU_surroundings / 2
- ΔU_system = ΔU_surroundings
- ΔU_system = 2 * ΔU_surroundings
- ΔU_system = -ΔU_surroundings (correct)
