Thermal energy is transferred in a method that can happen even if no air is present. This method of energy transfer is —

• convection

• condensation

• conduction

• radiation

The diagram shows an ice cube placed in a hot pan. Thermal energy is being transferred to the ice from the pan shown by

• convection

• condensation

• conduction

• radiation

Which picture best illustrates thermal energy transfer by conduction?

• Metal spoon in hot water

• Air warming above a radiator in a room

• The Sun warming the Earth

• Warming hand next to a fire

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

• Convection and conduction transfer energy through solids, liquids or gases.

• Radiation transfer energy through space in addition to solid liquid or gas

• Radiation requires direct contact between particles for energy transfer.

• Convection AND conduction use currents to transfer energy

What type of heat transfer occurs when you touch a metal seat with your hand and the seat feels cold?

• Radiation

• Convection

• Conduction

• Transpiration

What is an example of thermal energy transfer by radiation?

• A metal spoon becoming hot in a bowl of soup

• Water boiling in a pot on a burner on the stove

• The Sun heating the surface of the Earth

• A hot air balloon releasing gas and rising

Heat a nail to 100°C and place it into 20°C water. What will happen to the thermal energy of the water and the nail?

• Water transfer energy to nail until water and nail have equal temperature.

• Nail transfer energy to water until water and nail have equal temperature.

• The nail transfer energy to water/nail maintains its original temperature.

• The water transfer energy to nail/water maintains its original temperature.

An ice cube is placed onto a hot pan that is sitting on the counter top as shown. How will the thermal 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.

Graph shows temperature change that occurs when ice cube in beaker melts until the water reaches room temperature (20 C)

• Thermal energy in the room absorbs the cold from the ice cube.

• The ice cube absorbs thermal energy from the room.

• Thermal energy moves back and forth from the ice cube and the room.

• The ice cube gives thermal energy to the room.
