Theheat capacity of liquid water at constant pressure, `C_(P)` is `18 cal deg^(-1) mol^(-1)`. The value of heat capacity of water at constant volume, `C_(V)`, is approximately

A

`18 cal deg^(-1) mol^(-1)`

B

`16cal deg^(-1) mol^(-1)`

C

`10.8 cal deg^(-1) mol^(-1)`

D

cannot be predicted.

Text Solution

Verified by Experts

The correct Answer is:
B
`C_(P)=C_(V)=2 cal deg^(-1)mol^(-1)`
`C_(V)=C_(P)-2=18-2`
`=16cal deg^(-1)mol^(-1)`
