When a gas enclosed in a container of finite conductivity is suddenly compressed, the process

Options

Amay be very nearly adiabatic
Bmay be very nearly isothermal
Cmust be very nearly isothermal
Dmust be very nearly adiabatic

Correct answer

D. must be very nearly adiabatic

Step-by-step solution

When a gas is suddenly compressed, the time taken for the process is extremely small. Since the container has finite thermal conductivity, the heat exchange between the gas and the surroundings requires some time. Due to the sudden nature of the compression, there is practically no time for heat transfer to take place, meaning Q 0 . Therefore, the process must be very nearly adiabatic.
