Statement-I: it is possible for both the pressure and volume of a monoatomic ideal gas of a given amount to change simultaneously without causing the internal energy of the gas to change.
Statement-2: The internal energy of an ideal gas of a given amount remains constant it temperature does not change. it is possible to have a process in which pressure and volume are changed such that temperature remains constant.

Options

A. a cyclic process
B. an isothermal process
C. an adiabatic process
D. any process in which the heat given out the system is equal to the work done on the system
