How to find the temperature of the gas

In order to find the absolute temperature of an ideal gas, you can use the equation, which is commonly known as the equation of Clapeyron-Mendeleev. This formula allows to establish the relationship between pressure, temperature of gas and its molar volume.

You will need

• A sheet of paper, a pen.

Instruction

1. The formula is as follows: p•Vm = R•T where p is the pressure, Vm is molar volume of gas, R is the universal gas constant, and T is the absolute temperature of an ideal gas.
2. Find out what data is available to us in order to use the formula, thus: T = (p•Vm)/ R.
3. If we are not aware of molar volume of gas, we can find it by formula:
   Vm = V/?. In this formula ? represents the number of substances to Find this value is possible by dividing the mass of gas to its molar mass.
4. The formula, which is called the law of Mendeleev-Clapeyron, is written in this form: p•V = (m/M) • R•T.
5. Modifies this formula to find the temperature of the gas: T = (p•V • M)/(R• m).
6. Find all the values that require us to substitute into the formula. Calculations and find the desired temperature perfect gas.
