A sealed can of fixed volume contains air at a pressure of 102
kPa at 100
°C.
The can is then cooled to a temperature of 15.0
°C. Calculate the pressure of the air in the can

PV= nRT

n number of moles of gas is constant (sealed container)

V volume of container is constant
R is a constant value

Only variables are P pressure and T temperature
Convert temperature to Kelvin before calculating as is usual with this type of questio.
