1. Convection is the transfer of THERMAL ENERGY through liquids and gases.

2. In convection, the MOLECULES move from place to place and take their energy with them.

3. As gas and liquids get hot, the space between molecules expands, the substance becomes less dense, and the particles RISE.

4. As molecules LOSE thermal energy and cool down they become more dense and sink down.

5. The rising and falling of molecules moves the thermal energy through a LIQUID OR GAS.
