Question

I am not sure how to solve the problem since I haveonly one box to answer my question. Consider 1.70 mol of an idealdiatomic gas. (a) Find the total heat capacity of the gas atconstant volume and at constant pressure, assuming that themolecules rotate but do not vibrate.
Cp = 1 J/K

(b) Repeat, assuming that the molecules both rotate andvibrate.
Cp = 2 J/K I am not sure how to solve the problem since I haveonly one box to answer my question. Consider 1.70 mol of an idealdiatomic gas. (a) Find the total heat capacity of the gas atconstant volume and at constant pressure, assuming that themolecules rotate but do not vibrate.

Cp = 2 J/K (a) Find the total heat capacity of the gas atconstant volume and at constant pressure, assuming that themolecules rotate but do not vibrate.

(b) Repeat, assuming that the molecules both rotate andvibrate.
Cp = 2 J/K

Explanation / Answer

(a) molar heat capacity for an ideal diatomic gasis: . Cp = (7/2) n R = 3.5* 1.70 * 8.314 = 49.47 J/K . (b) If the molecules also oscillate, we expect... .     Cp = (9/2) n R = 3.5 * 1.70 * 8.314 = 63.60 J/K
