TERMS TO LEARN Heat – the transfer of energy between objects that are different temperatures Thermal energy – the total energy of the particles that make up a substance Conduction – the transfer of thermal energy from one substance to another through direct contact (touching)

TERMS TO LEARN Convection – the transfer of thermal energy by the movement of a liquid or gas Radiation – the transfer of energy through matter or space as electromagnetic waves, such as visible light and infrared waves.

METHODS OF HEAT TRANSFER Conduction Convection Radiation

CONDUCTION How it works When substances come in contact with each other, particles collide (hit each other) And thermal energy is transferred from the higher temperature substance to the lower temperature substance.

CONDUCTORS VS. INSULATORS Conductors are substances that conduct thermal energy very well Examples include: metals Insulators are substances that do not conduct thermal energy very well. Examples include: nonmetals, wood, styrofoam, plastic

CONVECTION How it works: See Figure 5 on p. 283 of text. 1. Water in the bottom of the pot gets hot. 2. The hot water gets less dense. 3. The warm water rises through the denser, cooler water above it. 4. The denser, cooler water on top of the pot sinks to the bottom of the pot.

CONVECTION The circular motion of liquids or gases due to differences in density because of temperature is called a convection current.

RADIATION How it works: See Figure 6 on p. 284 of text. Coils of heater warm a room by radiating visible light and infrared waves. Radiation and the Greenhouse Effect: See Figure 7 on p. 284 of text. Complete “Feel The Heat” WS.
