One mole of an ideal monoatomic gas is taken along the path ABCA as shown in
the PV diagram. The maximum temperature attained by the gas along the
path BC is given by :
Two moles of helium are mixed with n moles of hydrogen.
for the mixture, then the value of n is :
The value closest to the thermal velocity of a Helium atom at room temperature (300 K) in is : [ =1.4 × J/K; = 7 × kg ]
