State the S.I. unit of heat capacity.
The S.I. unit of heat capacity is :
(a) J kg−1 (b) J K−1
(c) J kg−1 K−1 (d) cal∘C−1
4.0 g of a gas occupies 22.4L at NTP. The specific heat capacity of the gas at constant volume is 5.0 JK-1mol-1. If the speed of sound in the gas at NTP is 952 ms-1, then the heat capacity at constant pressure is.
(Take gas constant R=8.3 JK-1mol-1)
