To find the absolute temperature of ideal gas, it is possible to use the equation which is widely known how Klapeyrona-Mendeleyev's equation. This formula allows to establish dependence between pressure, temperature of gas and its molar volume.

1. The formula looks as follows: p · Vm = R · T where p is pressure, Vm is the molar volume of gas, R is a universal gas constant, and T — absolute temperature ideal of gas.
2. We find out what data are available to us to use a formula, thus: T = (p · Vm)/R.
3. In case the molar volume of gas is not known to us, we can find it on a formula: Vm = V/?. In this formula? represents amount of substance, it is possible to Find this size having divided the mass of gas into its molar weight.
4. The formula which carries the name Mendeleyev-Klapeyrona's law registers in such look: p•V = (m/M) • R•T.
5. We alter this formula to find gas temperature: T = (p•V • L) / (R • m).
6. We find all sizes which are required for us for substitution in a formula. We carry out calculations and we find the required temperature of ideal gas.
