400 cm3 of oxygen at 27∘C were cooled to −3∘C without change in pressure. The contraction in volume will be
V2=T2T1.V1=270∘K300∘K.400 cm3=360 cm3 contraction=V1−V2=400−360=40 cm3
If 300 ml of a gas at 27∘C is cooled to 7∘C at costant pressure, then its final volume will be
300 ml of a gas at 27∘ C is cooled to - 3∘ C at constant pressure, the final volume is
