A 150-g quantity of a certain metal, initially at 120°C, is dropped into an insulated beaker containing 100 g of water at 20°C. The final temperature of the metal and water in the beaker is measured as 35°C. Assume that the heat capacity of the beaker can be ignored.
a. How much heat has been transferred from the metal to the water?
b. Given the temperature change and mass of the metal, what is the specific heat capacity of the metal?
c. If the final temperature of the water and this metal is 70°C instead of 35°C, what quantity of this metal (initially at 120°C) was dropped into the insulated beaker?
