The internal energy of one gram of helium at 100 K and one atmospheric pressure is
Text Solution
Verified by ExpertsThe correct answer is:
C
The helium molecule is monoatomic and hence its internal energy per molecule is 
(where 
is the Boltzmann, constant). The internal energy per mole is therefore is 
One gram of helium is one fourth mole and hence its internal energy is 
taking the value of R to be approximately 8J
