Specific heat at constant pressure: Heat absorbed by unit mass of a gas to raise its temperature by one degree, keeping the pressure constant, is called the specific heat of that gas at constant pressure (cp). So, heat taken by a gas of mass rn for rise in temperature t, at constant...
The heat capacity of a gas depends strongly upon the conditions under which heating is done, whether at constant pressure or at constant volume. Indeed, it was pointed out in Chapter 1 that the ratio C p / C υ is as high as 1.67 for a monatomic gas. It is possible to measure ...

Specific heat at constant volume, specific heat at constant pressure, specific heat ratio and individual gas constant - R - common gases as argon, air, ether, nitrogen and many more.
1. Understand the Definition of Specific Heat Ratio (γ): The specific heat ratio (γ) is defined as the ratio of the specific heat of a gas at constant pressure (C_p) to its specific heat at constant volume (C_v): γ=CpCv 2. Relate Specific Heat Ratio to Degree of Freedom: The...
specific heat 1.The ratio of the amount of heat needed to raise the temperature of a certain amount of a substance by one degree to the amount of heat needed to raise the temperature of the same amount of a reference substance, usually water, by one degree. Because molecules of different...
Thus, no work is done on a gas heated along a path of constantvolume; but work is done on a gas heated at constant pressure. In heating mostliquids or solids, the amount of external work is small compared to the amount ofheat absorbed as internal energy, so that the specif i c heat...
heat input per degree increase in temperature is the same in processes for which either the pressure or the volume is kept constant C. increase in the gas’s internal energy is greater when the pressure remains constant than when the volume remains constant D. pressure of the gas remains ...
