A calorimeter contains 195g of water initially at 20.4°C. A 37.8g sample of an unknown metal is heated to 133ºC and
placed into the water. Heat flows from the hot metal to the cold water until they both reach a final temperature of
24.6°C.
-Calculate amount of head gained by water (show your work plz)
-calculate specific heat of the metal (the amount gained by the water is equal to amount of heat lost by the metal)
