In an adiabatic compression, 200 J of work is done on a gas. What is the change in internal (thermal) energy of the gas during this compression?
A) 0 J
B) 200 J
C) -200 J
D) 100 J

Question

Quizplus · Accepted Answer

In an adiabatic process, there is no heat exchange with the surroundings. Therefore, the work done on the gas directly increases its internal energy by the same amount, which is 200 J.
