The data below was obtained from an experiment. Pressure(atm) Volumes(cm3) 1/p 1/v 1.0 10.00 2.0 5.00 2.5 4.00 4.0 2.50 7.5 1.33 10.0 1.00 …………(6) (c) From the above data, plot a graph of (i) P against V ……………(4) (ii) P against 1/v. ……………(4) (iii) Draw appropriate conclusion. ……………(2) 2. Use the kinetic theory to explain Boyles law. ……………(5)
(c) (i) The graph of P against V would be a curve that decreases as the volume increases.
(ii) The graph of P against 1/v would be a straight line that increases as the inverse of the volume increases.
(iii) The graph shows that as the volume increases, the pressure decreases, which is in accordance with Boyle's Law.
2. According to the kinetic theory, the pressure of a gas is a result of the collisions of the gas molecules with the walls of the container. As the volume of the container increases, the number of collisions with the walls decreases, resulting in a decrease in pressure. This is in accordance with Boyle's Law, which states that the pressure of a gas is inversely proportional to its volume.
