1.	A cylinder containing an ideal gas is in vertical position and has a piston of mass M that is able to move up or down without friction. Fig. if the temperature is increased.
Answer» both `p` and `V` of the gas will change. only `p` will increase according to Charle's law `V` will change but not `p`. `p` will change but not `V`. Solution :As piston is of fixed mass M, and it is able to MOVE up or down with out FRICTION, therefore, when temperature is increased, piston movesout, INCREASING the VOLUME V. The pressure p on the gas remains the same, because of fixed mass.
