a sample of oxygen has a pressure of 5.00 x 10^2 kpa
at 40.00° c. what will be the temperature in kelvin at a
pressure of 6.30 x 10² kpa?

Explanation:

Gay-Lussac's law states that at constant volume,the pressure of a gas is directly proportional to its temperature.

The pressure,temperature at any states with constant volume can be related as

where are pressure and temperature at initial state and are pressure and temperature at final state.
