The ammount of heat required to raise the temperature of 1 mole of diatomic gas by `1^(@)C` at constant pressure is `60cal` . The amount of heat which goes as internal energy of the gas is nearly.

A

60 cal

B

30 cal

C

42.8 cal

D

49.8 cal

Text Solution

Verified by Experts

The correct Answer is:
C
`q = DeltaH = 60 cal = nC_(P,m)DeltaT`
`DeltaU = nC_(Vm)DeltaT`
`rArr 60/(DeltaU) =7 rArr DeltaU = 60/(1.A) = 42.8 cal`
