# What is the value of CV for diatomic gas?

## What is the value of CV for diatomic gas?

The molar specific heat capacity of a gas at constant volume (Cv) is the amount of heat required to raise the temperature of 1 mol of the gas by 1 C at the constant volume. Its value for monatomic ideal gas is 3R/2 and the value for diatomic ideal gas is 5R/2.

## How do you calculate CP and CV values?

The specific heat of gas at constant volume in terms of degree of freedom ‘f’ is given as: Cv = (f/2) R. So, we can also say that, Cp/Cv = (1 + 2/f), where f is degree of freedom. Monoatomic gas has only one translational motion, hence three translational degrees of freedom.

What is a good gamma value?

Testing Gamma Typically, if you are running on the Windows operating system, the most accurate color is achieved with a gamma value of 2.2 (for Mac OS, the ideal gamma value is 1.8). So when testing monitors, we strive for a gamma value of 2.2.

### What gamma setting should I use?

A low gamma, with a shallow curve like the middle, is more appropriate for bright rooms and non-movie content. The higher gamma, on the right, is typically better for movies and darker rooms. In that example, all shadows (represented on the lower part of the curve), will be darker.
