A container contain 0.1 mole of 
and 0.1 mole of 
. If the gases are in thermal equilibrium then
A
Only the average kinetic energy of the molecule of 
and 
is same
and is same
B
Average speed of the molecule of 
and 
is same
and is same
C
Only the specific heat at constant pressure of two gases is same
D
The specific heat at constant pressure and the kinetic energy are same for both the gases
Text Solution
Verified by ExpertsThe correct answer is:
D
The specific heat at constant pressure ( 
) is the amount of heat required to raise the temperature of one gram through 
when the pressure of the gas is kept constant. Again, the mean kinetic energy per molecule 
depends only upon temperature. Clearly both the specific heats at constant pressure and mean kinetic energy are depending on the temperature which is again same for the two gases.
