Chapter 18, Problem 31SP

A 55-g copper calorimeter ( c = 0.093  cal/g ° C ) contains 250 g of water at 18.0 °C. When 75 g of an alloy at 100 °C is dropped into the calorimeter, the final resulting temperature is 20.4 °C. What is the specific heat of the alloy?

A coffee-cup calorimeter contains 55.0 g of water at 25.90° C. If 4.21 g gold metal at 89.20° C is placed in the calorimeter, what is the final temperature of the water in the calorimeter? The specific heat of water is 4.184 J/g° C; the specific heat capacity of gold is 0.129 J/g° C.
A 200 gram copper calorimeter contains 400 g of water at 25 °C. A metal specimen weighing 250 g is heated to a certain temperature and then plunged into the calorimeter. The final temperature of the mixture is 42 °C. If then specific heat of the metal specimen is 0.09 cal/(g-°C), find the initial temperature of the specimen just before it was plunged into the calorimeter
0.0550 kg piece of glass is heated to an unknown temperature and dropped into a calorimeter containing 0.150 kg of water at 12.0 °C. The glass and the water reach a final temperature of 18.0 °C. What is the initial temperature of the glass?
