Answer immediately please me volume of given mass ofa gas is 0.6 dm3 at a
pessure of 101.325K Pa. Calculate the volume of
the gas if its pressure is increased to 142.860KPa
at the same temperature (Ans. 0.426 dm3)
Z. A certain mass of a gas occupies a volume of 0.2
dm3 at 273K. Calculate the volume of the gas if
its absolute temperature is doubled at the same
pressure. (Ans. 0.4 dm3)
3. A flask has a volume of 0.25 dm3. What volume
of air will be displaced from the flask if it is heated
from 300K to 360K? (Ans : 0.05 dm3)
