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.
∴ P ᐃV is negative
Hence Cp - Cv < 0 ⇒ Cp < Cv.
