1.) What is the specific heat of a metal, in J/(g C), when 103.4 J is needed to raise the temperature of 2.85 g of the metal by 23.6 degree Celsius?

2.) Gold has a relatively low specific heat at 0.129 J/(g C). In other words, it does not take a lot of energy to change the temperature of gold. A property like that makes gold very useful in conducting heat and electricity from one location to another.

Suppose 10.2 kiloJoules is absorbed by a piece of Gold. When this happens, the temperature rises from 22.7 degrees C to 105.8 degrees C.

What is the mass, in grams, of this piece of gold?

3.) What is the amount of energy necessary, in kiloJoules, to raise the temperature of 45.5 grams of water from 100.0 degrees C to 150.0 degrees C ?

Specific Heat of water: 4.184 J/(g C)

4.) A 25.0 g piece of silver is currently at room temperature, 22.7 degrees C. Suppose that 0.125 kiloJoules of energy is absorbed by the silver. What is the final temperature of the piece of silver, in degrees Celsius?

Silver, Specific Heat = 0.235 J/(g C)
