Conduction is slower in gases than in liquids and solids because:

• gases have more tightly packed molecules than liquids and solids

• gases have more loosely packed molecules than liquids and solids

• gases have the same molecular structure as liquids and solids

• gases have a higher density than liquids and solids

Is the following sentence true or false? Conduction is faster in metals than in other solids because metals have free electrons that transfer thermal energy.

• True

• False

Circle the letter of each sentence that is true about conduction.

• a. Thermal energy is transferred without transfer of matter.

• b. Matter is transferred great distances during conduction.

• c. Conduction can occur between materials that are not touching.

• d. In most solids, conduction takes place as particles vibrate in place.

The transfer of thermal energy when particles of a fluid move from one place to another is called _________________.

• convection

• conduction

• radiation

• insulation

What is the most logical reason why the temperature would be significantly higher at the bottom of a closed oven?

• Hot air expands as it rises and then cools due to the expansion, making the top cooler.

• The only heating element is at the bottom.

• The bottom is insulated better.

• The oven door lets heat escape from the top.

• convection

• radiation

Circle the letter of each sentence that is true about radiation.

• Energy is transferred by waves.

• All objects radiate energy.

• The amount of energy radiated from an object decreases as its temperature increases.

• The farther away you are from a radiating object, the less radiation you receive.
