Document Summary
Chapter 2: warming the earth and the atmosphere. Temperature: a quantity that describes how warm or cold an object is with respect to some standard measure. It can also be described as the average speed of atoms or molecules in a substance (measure of kinetic energy). Kinetic energy: energy associated with the motion of an object. Heat: the transfer of energy into or out of an object because of temperature differences between that object and its surroundings. Heat travels form high temperature to low temperature. Heat is transferred by conduction, convention, and radiation. Sensible heat: the heat we can feel and measure with a thermometer. Latent heat: is the amount of energy required to change water form one state to another. This energy is used to break/form the molecular attractions that exist in different phases of water. In order for water to change phase, it must exchange heat with its surroundings.
