In which process, there is no change in the internal energy of the system?
Open in App
Solution
The correct options are
A Isothermal
C Free expansion
D Cyclic
In thermodynamics, the internal energy of a system is the
energy contained within the system, excluding the kinetic energy of motion of
the system as a whole and the potential energy of the system as a whole due to
external force fields. It keeps account of the gains and losses of energy of
the system that are due to changes in its internal state.
In case of isothermal, free expansion and cyclic process there is no change in the internal energy of the system as system's temperature remains constant in these processes. As internal energy is a function of temperature, there is no change in the internal energy of the system.
