What is the specific heat of CV?
CV is the specific heat at constant volume, and CP is the specific heat at constant pressure. Specific heat is the heat energy required to raise the temperature of a substance (per unit mass) by one degree Celsius.
What is the specific heat of air in Celsius?

What is the value of CP and CV?
The specific gas heat in terms of the degree of freedom ‘f’ at constant volume is given as: Cv = (f/2) R. So we can also assume that where f is a degree of independence, Cp/Cv = (1 + 2/f). Monoatomic gas has only one translational wave, thus three degrees of freedom in translation.
What is heat capacity of air?
about 700 Joules per kg per °K
Air has a heat capacity of about 700 Joules per kg per °K and a density of just 1.2 kg/m3, so its initial energy would be 700 x 1 x 1.2 x 293 = 246,120 Joules — a tiny fraction of the thermal energy stored in the water.
What is the specific heat ratio of air?
The nominal values used for air at 300 K are CP = 1.00 kJ/kg. K, Cv = 0.718 kJ/kg.

What is the value of CV for air?
0.718 kj/kg
At temperature 300 k, the values of air is: Cp = 1.005 kj/kg. Cv = 0.718 kj/kg.
What is CV of a gas?
The CV refers to the amount of energy released when a known volume of gas is completely combusted under specified conditions. The CV of gas, which is dry, gross and measured at standard conditions of temperature (15oC) and pressure (1013.25 millibars), is usually quoted in megajoules per cubic metre (MJ/m3).
What is high specific heat capacity?
A high specific heat capacity means it can hold a large amount of thermal energy in for a low mass or temperature change. It is also good at keeping in thermal energy, for example: Object: Mass = 3kg. ΔT = 10K.

Specific Heat Capacities of Air. The nominal values used for air at 300 K are C P = 1.00 kJ/kg.K, C v = 0.718 kJ/kg.K,, and k = 1.4.
How to calculate specific heat of air at constant pressure?
The calculator below can be used to estimate the specific heat of air at constant volum or constant pressure and at given temperature and pressure. The output heat capacity is given as kJ/ (kmol*K), kJ/ (kg*K), kWh/ (kg*K), kcal/ (kg*K), Btu (IT)/ (mol*°R) and Btu (IT)/ (lb m *°R) Temperature. Choose the actual unit of temperature: °C °F K °R.
