Heat Transfer

• Radiation
• Convection
• Conduction

2
Heat Facts

• Measured by thermometer
• 0O C is freezing point of pure water
• 100O C is boiling point of pure water
• Temperature is a measure of average kinetic
  energy (energy of motion)
• Thermal energy is the total energy of motion of
  molecules in a substance
• Heat flows from hot to cold.

3
Radiation

• Transfers heat from sun to Earth
• Doesnt require a gas, liquid, or solid for the
  transfer
• Microwave oven

4
Convection

• Transfer heat by movement through a fluid (air is
  a fluid)
• Explains most of the heating of the troposphere
• Heat waves rising off a road surface

5
Conduction

• Transfer of heat by direct contact
• Heat transferred from sand to the sole of your
