The total number of particles given by in an ideal gas of bosons of non-zero mass is 3/2 2x(2m) de b(e-h)-1 s. 1 n= eb1 0 (a) explain what is meant by each of the two terms in this equation. (there is to define the individual symbols.) no need [2 marks (b) briefly outline what is meant by the critical temperature tc. describe the properties of the gas at temperatures below te and explain how they arise. 5 marks] (c) near the critical temperature, the molar heat capacity at constant volume, cy, for a system of bosons is greater than the classical value of 1.5r. explain whether or not you expect the value to approach 1.5r at higher temperatures
