The aluminum cup inside your calorimeter weighs 39.96 g. You add 49.96 g of ice cold water to the calorimeter. You measure the temperature of the calorimeter to be 0.5oC just before your next addition. You then add 50.44 g of hot water and a 50.10 g metal object, all having an initial temperature of 69.5oC. After the calorimeter reaches thermal equilibrium, the final temperature is measured to be 36.1oC. Assume that: the calorimeter is completely insulated the heat capacity of the empty calorimeter is the heat capacity of the aluminum cup: 0.903 J g-1 oC-1. the density of water is: 1.00 g/mL. the heat capacity of water is: 4.184 J g-1 oC-1. Perform all calculations without rounding, but then provide your answer to the correct number of significant figures.

Part A

What is the change in heat, q, experienced by the cold water, in units of J?

Part B

What is the change in heat, q, experienced by the aluminum cup, in units of J?

Part C

What is the change in heat, q, experienced by the hot water, in units of J?

Part D

What is the change in heat, q, experienced by the metal object, in units of J?

Here we apply concept of calorimetry and heat balance equation. That is summation of change in heat of all individual elements will be zero.
