Asample of gas with a thermometer immersed in the gas is held over a hot plate. a student is asked to give a step-by-step account of what makes our observation of the temperature of the gas increase. his response include: (a) the molecules speed up. (b) then the molecules collide with one another more often. (c) internal friction makes the collisions inelastic. (d) heat is produced in the collisions. (e) the molecules of the gas transfer more energy to the thermometer when they strike it, so we observe that the temperature has gone up. (f) the same process can take place without the use of a hot plate if you quickly push in the piston in an insulated cylinder containing the gas

Consider a small frictionless puck perched at the top of a fixed sphere of radius r. if the puck is given a tiny nudge so that it begins to slide down, through what vertical height will it descend before it leaves the surface of the sphere? [hint: use conservation of energy to find the puck's speed as a func e conservation of energy to find the puck's speed as a function of its height at what value of this normal force does the puck leave the sphere? ] here on the puck.
