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

Calculate the ratio of h+ ions to oh– ions at a ph = 6. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 6. are they the same? why or why not? record your explanation in table a. what is the concentration of h+ ions at a ph = 6? mol/l what is the concentration of oh– ions at a ph = 6? mol/l what is the ratio of h+ ions to oh– ions at a ph = 6? : 1

As you are trying to move a heavy box of mass m, you realize that it is too heavy for you to lift by yourself. there is no one around to , so you attach an ideal pulley to the box and a massless rope to the ceiling, which you wrap around the pulley. you pull up on the rope to lift the box. use g for the magnitude of the acceleration due to gravity and neglect friction forces. once you have pulled hard enough to start the box moving upward, what is the magnitude f of the upward force you must apply to the rope to start raising the box with constant velocity? express the magnitude of the force in terms of m, the mass of the box.
