Song-era (10[1])Kaifeng housed the largest pre-modern example of a device (-5[1])named for this good, which the Greeks referred to as a clepsydra. Richard (10[2])Arkwright (10[1]-5[1])designed (-5[1])a powered device named for this (10[1])good (-5[1])that produced stronger (10[1])yarn than the spinning (10[1])jenny. (10[1]-5[9])Inscriptions (10[1]-5[3])from (-5[3])Sennacherib’s (-5[3])(“seh-NAK-eh-rib’s”) reign (-5[3])refer to a screw (-5[2])design for moving this good (10[8]-5[4])that (10[2])is (10[2])often (10[3])attributed (10[3]-5[2])to (10[1])Archimedes. (10[20]0[1]-5[2])The Persians (10[4])developed (10[2])an early (10[1])“wheel” (10[3])named for this good (10[2])that was adapted by medieval Europeans (-5[1])to mill grain. (10[4])For 10 points, name this liquid that’s heated to power steam (10[1])engines. (10[6])■END■ (10[27])
