6th Grade Energy Transformations & Thermal Energy

What is the definition of CONDUCTION?

• When heat is transferred from objects like rays of light or electromagnetically.
• a  hot liquid or air that  expands, becomes less dense, and rises or becomes more dense, and sinks.
• When heat transfers from objects that are touching.
• When heat transfers through the heater or AC in your house.

What kind of heat transfer happens when the sun is heating your body?

• Conduction
• Radiation
• Convection
• Density

A gas

• has a definite shape but no definite volume
• has a definite volume but no definite shape
• has fast-moving particles
