प्रश्न
In an ideal gas, the molecules possess
विकल्प
Only kinetic energy
Both kinetic energy and potential energy
Only potential energy
Neither kinetic energy nor potential energy
उत्तर
Only kinetic energy
Explanation:
In ideal gas, all the internal energy is in the form of kinetic energy, and any change in internal energy is accompanied by a change in temperature.
