2. Calorimetry Example
An unknown material of mass .062 kg and temperature 87°C is dropped into .35 kg of water at 20°C. When thermal equilibrium is reached, both have a temperature of 25°C. Calculate the specific heat capacity of the unknown substance.

3. Calorimetry
Problem:
A 0.40 kg iron horseshoe that is initially at 500 oC is dropped into a bucket containing 20 kg of water at 22 oC. What is the final equilibrium temperature?
Neglect any heat transfer to or from the surroundings.

4. Calorimetry
Problem:
A 200 g block of copper at a temperature of 90 oC is dropped into 400 g of water at 27 oC. The water is contained in a 300 g glass container. What is the final temperature of the mixture
