  • The free expansion of a gas into a vacuum.
  • The reversible isothermal expansion of an ideal gas.
  • The slow compression of a gas in a cylinder fitted with a frictionless piston
  • The rapid compression of a gas in a cylinder fitted with a frictionless piston.
Show Solution

The Correct Option is D

Solution and Explanation

In an adiabatic process, no heat is exchanged between the system and its surroundings, meaning \( Q = 0 \). Consequently, any change in internal energy is solely due to the work performed by or on the system.
