2 The measure of the average kinetic energy of the particles in an object Kinetic Energy=speed of molecules The higher the kinetic energy the higher the temperature

3 Temperature measures the average kinetic energy of particles Measured using a thermometer

4 The increase in volume of a substance due to an increase in temperature When kinetic energy increases the particles spread out from each other and expand

5 The transfer of energy between objects Energy is transferred from objects with higher temperatures to those with lower temperatures. Thermal Energy= the total kinetic energy of the particles

6 Methods of Heating Conduction Convection Radiation

7 Conduction- the direct transfer of energy from one object to another Conductors- substances that transfer heat well, ex. Metal Insulators- substances that do not transfer heat well, ex. Wood, styrofoam

8

9 The transfer of heat through a liquid or a gas Hot rises and cool sinks

10

11 The transfer of heat through space Radiation provides almost all of the energy we use on Earth

12

13 Specific Heat Capacity The amount of energy needed to change the temperature of 1kg of a substance by 1° Celsius

14 Determines how much energy is in a substance calorie= the amount of energy needed to change the temperature of.001kg of water by 1° C Kilocalorie= 1000 calories Calories are the units used on food labels

15 Calorimeter
