1. How much energy is necessary to raise the temperature from 20degrees C to 85 degrees C of a block of aluminum with a mass of 150g 2. There was 150 ml of water used to collect the energy from the marshmallow mass. The temperature was raised from 25 degreesC to 100 degreesC. Given the specific heat of water at 4.18J/g degreesC Approximately how much energy did the marshmallow give off?

3. If you use 1000J of energy to raise the temperature of a block of a mystery metal which has a mass 500g from 50 degrees C to 150degrees C. What is the specific heat of the mystery metal.

4. If you use 100J of energy to raise the temperature of a container of diamonds which has the specific heat of 0.519 .J/g degree C, How much do the diamonds weigh? Will the temperature rise if it starts at 20 degrees C and ends at 110 degree C.
