A gas container 1 mol of O_2 gas (specific molar mass 32) at pressure p and temperature T. In a similar container one mol of He gas (specific molar mass 4) is kept at temperature 2T. What is the pressure of this He gas?

A gas container 1 mol of O_2 gas (specific molar mass 32) at pressure

1.	A gas container 1 mol of O_2 gas (specific molar mass 32) at pressure p and temperature T. In a similar container one mol of He gas (specific molar mass 4) is kept at temperature 2T. What is the pressure of this He gas?
Answer» SOLUTION :Since number of moles and VOLUME are the same for both the GASES, using pV=nRT, it can be said that the pressure is directly proportional to the absolute temperature .Since temperature of the second container is double,pressure will also be double i.e., 2p.
