Document Summary
Gives water special properties like high surface tension and adhesion. Responsible for water being blue: thermal properties. Heat is the energy produced by random vibration of atoms or molecules. Flame has a higher temp but a tub of water have more heat and energy: heat capacity- ability to store heat. The measure of heat required to raise the temp of 1 gram of a substance by 1degree c. Calorie: the amount of heat required to raise the temp of 1 gram of water 1degree c. Waters heat capacity is equal to 1: temperature affects density, liquid is more dense than gas, temp increses, density decreases, change in state. Removal of heat energy is required to change water from liquid to solid: sensible heat loss: measure decrease in heat and in temp, latent heat of fusion: changes in heat, but not temp. Ice less dense than water resist a change in temp with a gain or loss of heat energy.
