1 Chapter 6 Thermal Energy Sections 1 and 2

2 Temperature The measure of the particle movement or kinetic energy of atoms and molecules in an object.

3 Absolute zero The lowest temperature possible (-273 °C) when no more energy can be removed from matter, or when particles are no longer moving.

4 Thermal Energy The total energy of all particles in matter.

5 Heat Movement of thermal energy from a high temperature to a low temperature.

6 Heat Transfer Conduction: Heat is transferred from one objects particles to another

7 Heat Transfer cont… Convection: The mass movement of heated liquid or gas. EX. Wind, oven, home heating system.

8 Radiation Transfer of energy through electromagnetic waves. EX: The sun

9 Conductors and Insulators A material that absorbs or conducts heat well is a conductor. EX: Metals

10 Conductors and Insulators Insulators are materials that do not conduct heat well and slow the transfer of energy. EX: Wood, wool, straw, Styrofoam

11 Specific Heat The amount of energy required to raise the temperature of 1Kg of a substance by one Kelvin. EX: water has a specific heat of 4.18J/KgxKelvin Units: J/KgxKelvin

12 Equation for change in Energy or transfer of thermal energy Mass x specific heat x change in temperature Heat added = specific heat x mass x (tfinal - tinitial )
