Heat Equation, Transfer and Calorimetry

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 is the definition of CONVECTION

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

What is the definition of RADIATION

•  hot liquid or air that  expands, becomes less dense, and rises or becomes more dense, and sinks.
• When heat is transferred from objects like rays of light or electromagnetically.
• 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?

This is a lava lamp. When the light bulb heats the wax, the wax rises. When the wax cools, it falls. This cycle of rising/falling is an example of:

• Conduction.
• Convection.
• Radiation.
