In a gas experiment, the pressure of the gas is plotted against the reciprocal of the volume of the gas at a constant temperature. the unit of the slope of the resulting curve is
force
force/m
work
force/m3
energy/m3
คำอธิบาย
slope = pressure \(\div\) \(\frac{1}{volume}\)
= \(\frac{N}{m^3}\) x \(\frac{m^3}{1}\)
= Nm = work
= \(\frac{N}{m^3}\) x \(\frac{m^3}{1}\)
= Nm = work
