A 4-mol ideal gas system undergoes an adiabatic process where it expands and does 20 J of work on its environment.How much heat is received by the system?

Question

Quizplus · Accepted Answer

In an adiabatic process, there is no transfer of heat between the system and its surroundings. Therefore, the work done on the surroundings (20 J) must come at the expense of the internal energy of the gas. Since the internal energy of an ideal gas is proportional to its temperature, this means that the temperature of the gas must decrease during the expansion. Since no heat is added or removed from the system, the answer is zero.
