  1. What is the difference between heat and temperature?

 

  1. Google the term specific heat. Write a definition. Cite your source.

 

For question 3:

  1. Go to the experiment and play the experiment.a) Describe what happens to the temperature of the water in comparison to the temperature of the sand.

    b) The specific heat of water is 4.18 J/g°C and the specific heat of sand is 0.85J/g°C. Relate this information to the temperature change you described in part a.
