Certain amount of a gas occupies a volume of 0.4 litre at 17°C. calculate the temperature at which the volume of gas is (a) doubled (b) reduced to half, pressure remaining constant?

The graph of PV vs P for a gas is :

1. parabolic
2. hyperbolic
3. a straight line parallel to X-axis
4. a straight line passing through origin

Volume-temperature relationship is given by :

1. Boyle
2. Gay Lussac
3. Dalton
4. Charles

If pressure is doubled for a fixed mass of a gas, its volume will become :

1. 4 times
2. 1⁄2 times
3. 2 times
4. No change
