The principal specific heat of hydrogen ...

The principal specific heat of hydrogen gas at constant pressure and at constant volume are 3400 cal/kg `.^(K)` and 2400 cal/kg `.^(@)K` respectively. Then the value of J will be (R=8300 J/kmol K, mol wt of `H_(2)=2`)

A

4.18

B

4.17

C

4.16

D

4.15

Text Solution

Verified by Experts

The correct Answer is:
D
`C_(p)-C_(V)=(R)/(JM)`
`J=(R)/((C_(p)-C_(V))M)=(8300)/((3400-2400)2)`
`=(8300)/(1000xx2)=(8.3)/(2)=4.15`
