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 in a four-stroke engine, while it causes autoignition in diesel engines. Air undergoes this process at every peak of a sound wave. The surroundings do positive PV work on the system in this process, which occurs in the last 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. For 10 points, name this process in which a gas is forced into a smaller volume. ■END■
