Molar specific heat of oxygen at constan...

Molar specific heat of oxygen at constant pressure is 7.2 cal/mol `.^(@)C` and R=8.3 J/mol K. at constant volume, 5 moles of oxygen is heated from `10^(@)C` to `20^(@)C` then the quantity of heat required will be

A

25 cal

B

50 cal

C

260 cal

D

500 cal

Text Solution

Verified by Experts

The correct Answer is:
C
`C_(V)=C_(p)-R`
`=7.2-2=5.2`
`dQ_(V)=nC_(V)dT`
`=5xx5.2xx10=260cal`.
