Answer) Curve 2 represents the behaviour of gas at higher temperature. On increasing the temperature the kinetic energy of the molecule is increased and hence their collision is increased as a result of which the speed of the molecules changes. On increasing the temperature molecular speed also increases which is clear from curve 2.
