What is the specific heat of the gas?

Principal Specific Heat of Gas at Constant Volume: The quantity of heat required to raise the temperature of a unit mass of gas through 1 K (or 1 °C) when its volume is kept constant, is called its principal specific heat at constant volume. It is denoted by cV. Its S.I. unit is J K-1 kg-1.

What is specific heat of gas and its types?

The ratio of the specific heats γ = CP/CV is a factor in adiabatic engine processes and in determining the speed of sound in a gas. This ratio γ = 1.66 for an ideal monoatomic gas and γ = 1.4 for air, which is predominantly a diatomic gas.

What is CP CV ratio?

The Cp/Cv ratio is also called the heat capacity ratio. In thermodynamics, the heat capacity ratio is known as the adiabatic index. Cp/Cv ratio is defined as the ratio of two specific heat capacities. (i.e.) Heat Capacity ratio = Cp/Cv = Heat capacity at constant pressure/ Heat capacity at constant volume.

What is Q in heat capacity formula?

Q = m•C•ΔT where Q is the quantity of heat transferred to or from the object, m is the mass of the object, C is the specific heat capacity of the material the object is composed of, and ΔT is the resulting temperature change of the object.

What is the correct formula for determining specific heat?

Once you become familiar with the terms used for calculating specific heat, you should learn the equation for finding the specific heat of a substance. The formula is: Cp = Q/mΔT . You can manipulate this formula if you want to find the change in the amount of heat instead of the specific heat.

How is specific heat calculated?

The formula for specific heat looks like this: c = Q / (m * ΔT) Q is the amount of supplied or subtracted heat (in joules), m is the mass of the sample and ΔT is the difference between the initial and final temperature of the sample.

What is the value of specific heat?

For liquid at room temperature and pressure, the value of specific heat capacity (Cp) is approximately 4.2 J/g°C . This implies that it takes 4.2 joules of energy to raise 1 gram of water by 1 degree Celsius. This value for Cp is actually quite large.

What instrument is used to calculate specific heat capacity?

The calorimeter is most often used to determine specific heats of materials.
