In a gas experiment, if the volume of the gas is plotted against the reciprocal of the pressure, the unit of the slope of the resulting curve is

Answer Details

IF the volume of gas is plotted against the reciprocal of pressure, the slope will be given as Slope = V/1/P = P x V thus the unit of the slope will be;

P =

Force

Area

= Nm-2, = V = M3 = NM. The unit NM (Newton - Meter) is the practical unit of work, which is the product of force (N) and Displacement (M). Note: It should be noted that the practical unit of work is Newton-Meter, whereas its S.I unit is Joules, just as energy.
