Thermal Characteristics of Water


1) Are heat and temperature same or different? Why?
- Different. Temperature is a physical property that underlies the common notions of hot and cold.

2) What is the heat capacity of water?
- 1GM of water needs 1 calorie of heat to raise its temperature by 1°C.

3) How is the heat capacity of water unique?
- When molecules are heated, they move faster and get more energy. Because the O take e- from the H atoms to gain a stable octet.

4) How does water temperature affect density?
- The warmer the water, the less dense it is. The colder the water, the Morse dense it is.
