Review of : Heat, Temperature & Thermal Energy
Heat flow of energy from objects is a _______ higher at a _____ temperature to objects at a _____ temperature. lower �Heat �Soon after you put ice cubes into a pitcher of lemonade, energy is transferred from lemonade to the colder ____. the warmer _____ ice HEAT FLOWS FROM WARMER COOLER!!!
Temperature �Temperature is a measure of the average kinetic energy of all the _____ particles in an object. �If a liquid, such as hot cocoa, has a high temperature, the particles in the liquid are Very fast high moving _____, and have a _______ average kinetic energy. �If a drink, such as a fruit smoothie, has a low temperature, the particles in the liquid More slowly and have a are moving _____ low _______ kinetic energy
Thermal Energy total kinetic energy is the _______ energy of particles in an object. �Note that temperature and thermal energy are different from each other. average while Temperature is an _____ thermal energy is a ______. total �A glass of water may have the same temperature as the Mississippi River, but less thermal energy because will have _____ there are less water particles in the glass of water. �Thermal
Review of Conduction, Convection, and Radiation
Conduction �Conduction is the process that moves energy from one object to another when physically they are Touching ________. �Conduction occurs any time that objects different temperature come into at a _____ contact with each other. �Conduction can also occur within a single object. In this case, energy is transferred warmer part of the object to the from the ______ cooler part of the object. _______
Convection �Convection is the process that transfers energy by the movement of particles in liquid the same direction in a _____ or gas ____. more dense will �Cool air/water that is _____ less dense, air/water push warmer, _____ upwards. Once that warm air/water more dense once again cools, it becomes _____ and settles back down to the bottom to start the process all over again.
Radiation �Radiation is energy that travels as electromagnetic waves, which includes _______ visible light and microwaves. Sun is the most significant source of �The ____ radiation that you experience on a daily basis. �Like both conduction and convection, radiation can transfer energy from a ______ warmer object to a _______ one. cooler differs from conduction �However, radiation and convection because radiation can travel through _______, as it does when it Empty space moves from the Sun to the Earth.
