Tossup

This process is performed on saturated liquids like R22 before condensation and throttling steps in most air conditioners. This process (10[1])is performed immediately before a spark plug ignites fuel (10[1]-5[1])in a four-stroke engine, (-5[1])while it causes (10[1])autoignition in diesel engines. Air undergoes this process at every peak of a sound wave. (10[1])The surroundings do positive PV work on the system in this process, which occurs in the last (10[1])two steps of the Carnot (“kar-NO”) cycle. This process, which increases pressure by Boyle’s law, is performed by lowering a piston and typically follows an expansion step. (10[1])For 10 points, name this process (-5[1])in which a gas is forced into a smaller volume. (10[2])■END■
