Question: P _ 0 1 : When 4 0 0 J of work are done ON a system the change in the systems thermal energy is

P_01: When 400 J of work are done ON a system the change in the systems thermal energy is observed
to be -200 J (i.e the thermal energy decreases by 200 J).
Q-01: What is the heat transfer? A positive value indicates heat energy is transferred into the system
and a negative value indicates the energy is transferred out of the system.
__________ J
