A science teacher sets up a demonstration for her class. She turns on three electric hot plates. On each hot plate is a beaker of water. Between the hot plate and the beaker is a block of material: metal, granite, or glass. The blocks are all the same size. The water in the beaker
above the metal block boils first.
Why does the water in the beaker on the metal block boil first?
O A Metal lets out more heat than the other substances,
O B. Metal is a harder material than the other substances,
O c. Metal transfers heat faster than the other substances,
OD. Metal is better at reflecting heat than the other substances,
