Down
- 1. The circular pattern that particles move in during convection
- 3. A type of solar heating that uses machines and devices
- 4. A type of central heating system that distributes heated air through a building use convection currents
- 5. A material that allows heat to easily pass through
- 8. One of the components of active solar heating. An example of this would be a solar panel.
