Pressure of an ideal gas is increased by keeping temperature constant. The kinetic energy of molecules
Text Solution
Verified by ExpertsThe correct answer is:
C
: The kinetic energy of molecules of an ideal gas is
where 
is the number of molecules, 
is the Boltzmann constant and 
is the temperature of the gas.
From the above expression it is clear that 
depends on the temperature but not on the pressure, volume and nature of the gas.
Thus, on increasing the pressure by keeping the temperature constant, the kinetic energy of molecules remains same.
