Document Summary
A quantity that describes how warm or cold an object is with respect to some standard measure. Can also be described as the average speed of atoms or molecules in a substance (measure o kinetic energy) Transfer of energy into or out of an object because of temperature differences between that object and its surroundings. Heat travels from regions of high temperature to regions of low temperature. Sensible heat: heat we can feel and measure with a thermometer. Latent heat: the amount of energy required to charge water from one phase to another (solid, liquid, gas). This energy is used to break or form molecular attractions that exist in different phases of water. Melting, evaporation and sublimation cool the atmosphere. Freezing, condensation and deposition warm the atmosphere. How does the atmosphere warm during the day: conduction, convection (and advection, radiation. Conduction can only warm the bottom few centimeters of the atmosphere.
