Answer #1

Actually Pressure proportional to temperature at constant volume is Gay Lussac's law.

From ideal Gas equation PV = nRT

                                   P = nRT / V

                                   P = (nR/V) T

if draw graph between pressure and temperature by keeping volume constant you will get a straight line originating from '0' . Then the equation of that line is

    P = (nR/V) T    ( y = m x , where m = slope)

Then in this case slope = nR / V

A physicists performs an experiment to evaluate the number of moles of a gas inside a container. The container is kept at constant room temperature of 23°C and is built in such a way that the number of moles stays constant. The physicist changes the volume to different values and measures the corresponding (absolute) pressures. The table below shows the results of the experiment.
