Thermal Characteristics of Water

1. Are heat and temperature same or different? Why?
Temperature is a physical property that is intensive. While heat is energy transferred from one body to another; and it is extensive.

2. What is the heat capacity of water?
4.18*10^3 J/kgK

3. How is the heat capacity of water unique?
It has a very large specific heat.

4. How does water's temperature affect its density?
Volume generally increases with temperature thus creating a change in its density.
