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 (10[1])a spark plug (10[2])ignites (10[3])fuel (10[3]-5[1])in a (10[1])four-stroke (10[10]-5[1])engine, (10[9]-5[4])while it causes (10[1])autoignition (10[6]-5[1])in (10[1])diesel (-5[1])engines. (10[6]-5[3])Air (10[1])undergoes (10[2])this (10[1])process (10[4])at every (10[1]-5[1])peak (10[1])of a sound (-5[2])wave. (10[7]-5[2])The (10[2])surroundings (10[7])do positive PV (10[1])work (10[1])on the system (-5[1])in (10[1])this process, (10[1]-5[1])which (10[1])occurs in the last (10[1])two steps (10[1]-5[1])of the Carnot (“kar-NO”) cycle. (-5[1])This process, which increases pressure by Boyle’s law, (-5[1])is (10[1])performed (10[1])by lowering a piston and typically (10[1])follows (10[1])an (10[1])expansion step. (10[3])For 10 points, name this process (-5[1])in which a gas is forced into (-5[1])a smaller volume. (10[2])■END■ (10[18]0[2])
