If the volume of a gas is doubled at constant pressure, the average translational kinetic energy of its molecules will
1 Remains the same
2 Be doubled
3 Become four times
4 Increase by a factor
Explanation:
If volume is doubled at constant pressure, then absolute temperature of the gas is doubled. So, average translational kinetic energy is also doubled.
