Tossup

This process is performed on saturated liquids like R22 before condensation and throttling steps in most air conditioners. This process is performed immediately before a spark plug ignites fuel (10[1])in a (10[1])four-stroke (-5[1])engine, (-5[1])while it causes autoignition in diesel engines. (10[2]-5[1])Air undergoes this process at every peak of a sound wave. The surroundings (10[1])do positive PV work on the system in this process, which occurs in the last two steps (-5[1])of the Carnot (“kar-NO”) cycle. (-5[1])This process, which increases pressure by Boyle’s law, is performed (10[1])by lowering a piston and typically follows an (10[1])expansion step. For 10 points, name this process in which a gas is forced into a smaller volume. ■END■ (10[4]0[1])
