A 37.0g sample of polyisoprene, which has a specific heat capacity of 1.880 J·g−1°C−1, is dropped into an insulated container containing 150.0g of water at 55.0°C and a constant pressure of 1 atm. The initial temperature of the polyisoprene is 5.2°C.

Assuming no heat is absorbed from or by the container, or the surroundings, calculate the equilibrium temperature of the water.

Be sure your answer has 3 significant digits.

Calculate the final temperature of the water from the following heat transfer experiment. 14 g of water at an initial temperature of 61 oC (Celsius) is added to 100.0 g of water at 100.0oC. The experiment is performed in an insulated container to prevent heat loss to the surroundings. Specific heat of water = 4.184 J/(g oC) State your answers in degrees celsius (C) with 3 significant figures.
