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