Question

Which is an adiabatic process?

• A. The free expansion of a gas into a vacuum.
• B. The reversible isothermal expansion of an ideal gas.
• C. The slow compression of a gas in a cylinder fitted with a frictionless piston
• D. The rapid compression of a gas in a cylinder fitted with a frictionless piston.

Hint:

In an adiabatic process, there is no heat transfer, and the system's energy changes only due to work.

Answer 1

The Correct Option is D

An adiabatic process is one in which there is no heat exchange between the system and its surroundings. An adiabatic process is one where no heat is exchanged with the surroundings, i.e., \( Q = 0 \). In this process, the change in internal energy is equal to the work done by or on the system.
