Assertion :For a given amount of an ideal gas, a plot of pressure (p) versus (1/V) is a straight line at a constant temperature. Reason :A given amount of an ideal gas at a constant temperature obeys Boyle’s law.

For a given amount of ideal gas at constant Temperature, Boyle’s law is obeyed. Boyle’s law states, 1 P V [ amount of gas temp should be constant] K P = V [ where K = nRT ] Thus, plot of 1 P vs v gives straight line. (y = mx form)
