Question 1

Which of the following substances has the greatest specific heat?

copper

ice

water

steam

Ice, water, and steam have equal specific heats since they are the same material, and this specific heat is greater than that of copper.


Question 2

Which statement below regarding the First Law of Thermodynamics is most correct?

A system can do work externally only if its internal energy decreases.

The internal energy of a system that interacts with its environment must change.

No matter what other interactions take place, the internal energy must change if a system undergoes a heat transfer.

The only changes that can occur in the internal energy of a system are those produced by non-mechanical forces.

The internal energy of a system cannot change if the heat transferred to the system is equal to the work done by the system.
