GEOG 131 Chapter 2.3-2.4: Geog 131 Ch 2.3 Notes
Document Summary
Temperature- measure of the object"s internal kinetic energy- the energy contained within molecules that are moving. Heat- thermal energy transferred from one object to another: joule- a measure of work of energy. Sensible heat- changes the temperature of two objects through exchange. Radiosondes- measure of a range of variables at various heights as the balloon ascends. Absolute zero- no internal energy exists and all molecular motion theoretically ceases: -273c or -460f. Latent heat- considerable quantities of energy contained. Latent hear of fusion- latent heat associated with melting. Evaporation- conversion from a liquid to vapor phase. Condensation- when gas molecules are cooled and recombine into a liquid. Latent heat of vaporization- latent heat associated with evaporation and condensation. Sublimation- going directly from solid to vapor state: latent heat of sublimation. Deposition- converting water vapor directly into ice. 80% of energy goes into changing state, 20% into changing temperature. High energy states- phases that require more energy to form: vapor.
