Document Summary
Temperature: quantity that describes how warm or cold an object is with respect to some standard of measure. Temperature can also be described as the average speed of atoms or molecules in a substance measure of kinetic energy. Kinetic energy: energy that is associated with motion of an object. Three units of measure for temperature: fahrenheit, celsius and kelvin. Heat: transfer of energy into or out of an object b/c of temperature differences between the object and surrounding: heat travels from high to low temps. Sensible heat: heat we can feel and measure w/ thermometer. Latent heat: amount of energy required to change water from one state to another this energy is used to break/form molecular attractions that exist in different phases of water. Solid (ice) liquid (water) gas (water vapor: solid liquid gas = sublimation. To change phase, water must exchange heat w/ its surroundings: heat is measured in unites of calories.
