The molar specific heat of oxygen at constant pressure `C_(P) = 7.03 cal//mol .^(@)C` and `R = 8.31 J//mol .^(@)C`. The amount of heat taken by 5 mol of oxygen when heated at constant volume from `10^(@)C` to `20^(@)C` will be approximately.

A

25 cal

B

50 cal

C

250.5 cal

D

500 cal

Text Solution

Verified by Experts

The correct Answer is:
C
`dQ_(V)=nC_(V)dT`
`=5xx(C_(p)-R)dT`
`=5(7.03-2)xx10=5xx5xx10`
=250 cal
