# Specific Heat Capacity

• The specific heat of a gas in the quantity of heat required to rise the temperature of unit mass of gas through K, \tt C=\frac{1}{m}\left(\frac{dQ}{dT}\right)
• The molar specific heat of gas is the quantity of heat required to rise the temperature of unit mole of a gas through 1k, C = \tt \frac{1}{n}\left(dQ\diagup dt\right)
• The relation between Cp and Cv is Cp − Cv = R
• The relation between Cp and Cv is Cp − Cv = r.
• The ratio of specific heats Cp/q = γ

1. The change in temperature of a substance, when a given quantity of heat is absorbed or rejected by it, is characterised by a quantity called the heat capacity of that substance. We define heat capacity, S of a substance as \tt S=\frac{\Delta Q}{\Delta T}

2. The specific heat capacity, of that substances is given by \tt s=\frac{S}{m}=\frac{1}{m}\frac{\Delta Q}{\Delta T}

3. Molar heat capacity, it is given by \tt C=\frac{Q}{n \Delta T}
