When water is heated from `0^(@)C` to `4^(@)C` and `C_(P)` and `C_(V)` are its specific heats at constant pressure and constant volume respectively , then :-

Options

A. `C_(P)gt C_(V)`
B. `C_(P)lt C_(V)`
C. `C_(P) = C_(V)`
D. `C_(P) - C_(V) = R`

Answer

B

Explanation

When water is heated from `0^(@)C` to `4^(@)C` , its volume decreases.
` therefore P DeltaV` is negative
Hence `C_(P) - C_(V) lt 0 implies C_(P) lt C_(V)`
