A 50.0 g sample of a metal at 225 °C is dropped into 450.0 g of water at 22.0 °C. If the final temperature of the system is 25.5 °C, what is
the specific heat of the metal?

What amount of heat is exchanged when 106.2 grams of substance y goes from a liquid at 35 degrees celsius to a solid at the same temperature? melting point of substance y = 35 degrees c; δhvaporization = 3.67 j/mol; δhfusion = 3.30 j/mol. mwsubstance y = 28.22 g/mol. −12.4 j −3.51 x 102 j 1.24 x 101 j 351 j
