You are standing with your back to a campfire. You notice that your back is much warmer than your chest. You know that thermal energy is being transferred from the fire. This method of energy transfer is -

• CONDUCTION

• CONVECTION

• RADIATION

• CONDENSATION

While drinking a cup of hot chocolate, on a cold winter night, you know that the hot liquid is transferring energy into the surrounding air. The heated air over the cup of hot chocolate expands and rises, as steam, and is replaced by cooler, denser air. This method of energy transfer is -

An ice cube is placed into a hot pan, that is sitting on the stove. How will the energy move?

• The coldness will move from the pan to the ice cube

• The coldness will move from the ice cube to the pan

• The heat will travel from the pan to the ice cube

• The heat will move from the ice cube to the pan

A pot of water is placed on a hot plate. The hot plate is turned on and the water begins to boil. What 2 forms of energy transfer occur?

• Radiation occurs where the hot plate touches the pot. Convection occurs in the movement of the boiling water

• Conduction occurs where the hot plate touches the pot. Radiation occurs in the movement of the boiling water.

• Convection occurs where the hot plate touches the pot. Conduction occurs in the movement of the boiling water.

• Conduction occurs where the hot plate touches the pot. Convection occurs in the movement of the boiling water.

A metal spoon in hot water represents what type of energy transfer?

• CONVECTION

• RADIATION

• CONDUCTION

• HEAT

How does transfer of energy by radiation differ from convection & conduction?

• Convection & Conduction transfer thermal energy through solids, liquids & gases

• Radiation can transfer energy through space in addition to solids, liquids & gases

• Radiation requires direct contact for thermal energy transfer

• Convection & Conduction use currents to transfer thermal energy in solids, liquids & gases
