Molar heat capacity is heat required to raise the temperature of one mole of material by one degree, since heat is not a state function, the amount of heat required to produce a given change in its state depends on the path followed.
`C_P="specific heat" xx "Molecular weight"`. It is measured at constant pressure
`C_V="specific heat" xx "Molecular weight"`. It is measured at constant volume
Answer the following questions based on above passage:
The specific heat of a gas at constant volume is 0.075 cal/g. Predict the atomicity of the gas. Molar mass of gas is `40 g mol^-1`
