at 25degreesC and 100Kpa a gas occupies a volume of 20dm(cubed) . calculate the new temp of the gas if:

a) the volume is decreased to 10dm(cubed) at constant pressure
b) the pressure is decreased to 50kPa at constant volume





also im not sure if the answer for temp would come out in degreesC or K (kelvin)
thanks xx
