What is the temperature of a 100 liter container having 1 mole of an ideal gas at a pressure of 20 kilopascals?
This can only occur at a temperature of 240.5 kelvin (-32.6 °C).
For an ideal gas, the relationship among pressure, volume, quantity and temperature is the ideal gas law
This essentially tells us that if we specify any three of
Using the values stated in this problem,
The only temperature for which the stated conditions could exist would be at a temperature of 240.5 kelvin (-32.6 °C).
