Stoichiometry - Engineering

Q1:

Cp - Cv, for an ideal gas is equal to

A R

B R/2

C 2R

D 3R

ANS:A - R

For an ideal gas, the difference between the molar specific heat at constant pressure (𝐢𝑝Cp​) and the molar specific heat at constant volume (𝐢𝑣Cv​) is a constant value. This difference is given by: 𝐢𝑝−𝐢𝑣=𝑅Cp−Cv=R where 𝑅R is the gas constant. So, the correct answer is 𝑅R.
