C)heat exchanged with the surroundings is zero.
D)pressure on the air parcel remains constant.
E)work done is zero.

Question

Quizplus · Accepted Answer

An adiabatic process is one in which there is no heat exchange with the surroundings. This means that the energy of the system is conserved, and any changes in the system must be due to work done on or by the system. The temperature, pressure, and altitude of the air parcel can all change during an adiabatic process, as long as there is no net heat transfer. Therefore, choices A, B, and D are incorrect. Similarly, while the work done on or by the system may be non-zero during an adiabatic process, the lack of heat exchange is the defining characteristic of an adiabatic process. Therefore, choice E is also incorrect.
