Thermal Energy

1. What forms of energy transfer occur while the hot plate is turned on?

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

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

• Convection occurs where the hot plate touches the beaker.

  Conduction occurs in the movement of the water.

• Conduction occurs where the hot plate touches the beaker.

  Convection occurs in the movement of the water.

Which statement best describes what is happening when water is thrown on a wood fire?

• The water transforms the thermal energy to chemical energy.

• The water causes a chemical change of the wood which reduces the fire.

• The water releases its thermal energy to the fire.

• The water absorbs the thermal energy of the fire.

Which type of thermal energy transfer is illustrated in the diagram shown above?

• Electromagnetic waves of radiation

• Direct transfer of thermal energy by conduction

• Heat rising, cooling, and sinking by convection

• All three types of thermal transfer are illustrated

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

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

• Radiation can transfer thermal energy through space in addition to solids, liquids, or gases.

• Radiation requires direct contact between particles for thermal energy transfer.

• Convection and conduction use currents to transfer thermal energy in solids, liquids, or gases.

A bottle of water at a room temperature of 21.0°C is placed into a refrigerator with an air temperature of 4.5°C. The thermal energy will move —

• from the cooler air to lower the temperature of the water to 4.5°C

• in both directions until the temperature is equal in the water and the air

• from the water to the air until the water temperature is zero degrees Celsius

• from the water to the air until the temperature is equal in both
