CO2 is stored in a pressure bottle with a volume of 0,08m^3 at a temperature of 18 ° C. The pressure gauge shows a pressure of 360kpa. CO2 should be approximated as an ideal gas. For the specific heat capacity, the true specific heat capacity at 0 ° C should be used.

What pressure does the pressure gauge display when the temperature of the gas rises due to a fire in the building where the bottle rises to 212 °C?

Give answer in kPa and round to the nearest one.
