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
The correct answer is: D
Explanation
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.
