(a) The specific heat capacity at constant volume (c v) is defined as the quantity of heat required to raise the temperature of 1 kg of the gas by 1 K if the volume of the gas remains constant.he molar heat capacity at constant volume (C V) is the quantity of heat required to raise the temperature of 1 mole of the gas by 1 K if the volume of the gas remains constant.
There are two main types of gas thermometer, one operating at constant volume and the other at constant pressure. The constant-volume gas thermometer is by far the more widely used and so we will deal with it alone.The ideal gas equation states that for n moles of a gas: PV = nRT. and therefore for a gas at constant volume V the absolute temperature T is directly proportional to the pressure of the gas P. simple form of constant-volume gas thermometer is shown in Figure 1. The gas is enclosed in the bulb B and the pressure recorded by the difference in levels (h) of the mercury columns.
