Question

For an ideal gas, Cy and Cp are related as:

(a) Cv - Cp = R

(b) Cv + Cp = R

(C) Cp - Cv = RT
(d) Cp-Cv=R

Answer 1

For an ideal gas, the relationship between the specific heat capacities at constant volume \( C_v \) and at constant pressure \( C_p \) is given by:

\[
C_p - C_v = R
\]

where \( R \) is the ideal gas constant.

Thus, the correct answer is:

**(d) \( C_p - C_v = R \)**.
