1.	Assertion : On reducing the value of a gas at constant temperature, the pressure of the gas increase. Reason : At constant temperature according to Boyle's law, volume is inversely proportional to pressure.
Answer» If both assertion and reason are TRUE and the reason is correct explanation of the assertion. If both assertion and reason are true but reason is not the correct explanation of assertion. If assertion is true, but the reason is false. If assertion is false but the reason is true Solution :ACCORDING to BOYLE's law at constant temperature `P prop 1/V` when the number of MOLECULES increase per unit volume. Because of it more molecules collide on the walls of vessel per second hence number of collisions per second increases therefore, a greater MOMENTUM is transferred to the walls of vesseles per second and hence, the pressure of gas increases.
