Kinetic theory of gases past paper questions

A2 Physics 9702 · Ideal gases. 1 state the basic assumptions of the kinetic theory of gases 2 explain how molecular movement causes the pressure exerted by a gas and derive and use the relationship pV = 3 1 Nm<c2>, where <c2> is the mean-square speed (a simple model considering one-dimensional collisions and then extending to three dimensions using 3 1 <c2> = <cx 2> is sufficient) 3 understand that the root-mean-square speed cr.m.s. is given by c < > 2 4 compare pV = 3 1 Nm<c2> with pV = NkT to deduce that the average translational kinetic energy of a molecule is 2 3 kT, and recall and use this expression
