Question

Which of the following is a FALSE statement?

• A. Heat is energy transferred into or out of a system as a result of a temperature difference between the system and its surroundings.
• B. The heat added to an ideal gas during the transition from state 1 to state 2 depends only on the initial and final states, 1 and 2, and not on the path by which the gas went from one to the other.
• C. When a gas goes from one state to another, the work done depends on the path followed
• D. It does not make sense to refer to "the amount of heat in a body".

Answer 1

Answer: (B)

The heat added to an ideal gas during the transition from state 1 to state 2 depends only on the initial and final states, 1 and 2, and not on the path by which the gas went from one to the other.

Answer 2

Heat is a path function. Heat transfer depends on process. Hence heat transfer is different for different paths between same initial & final status.
