Which of the following statement is false for an isothermal expansion of an ideal gas
Options
(a) Average kinetic energy of the molecules increases
(b) Number of molecules per unit volume decreases
(c) Pressure of the gas decreases
(d) Volume of the gas increases
Correct Answer:
Average kinetic energy of the molecules increases
Explanation:
As E∝T. Since in isothermal process temperature remains constant.Hence Kinetic energy will also remain constant.
