Heat and Thermal ExpansionHard

Question

When water  is heated from 0oC to 4oC  and CP and CV are specific heats at constant pressure and constant volume respectively, then : -

Options

A.CP > CV
B.CP < CV
C.CP = CV
D.CP - CV = R

Solution

When water is heated  from 0oC to 4oC , its volume decrease.
 ∴ P ᐃV is negative
Hence Cp - Cv < 0 ⇒ Cp < Cv.
