Heat Transfer Review

What conditions are necessary for heat conduction to occur between two objects?

• The objects must be surrounded by air or water.

• Two objects at different temperatures are touching one another.

• Two objects at different temperatures are located close to one another.

• One object must emit energy as light and heat and another object absorbs the energy.

Manuel was having trouble opening a new glass jar of pickles. His father told Manuel to hold the metal lid of the jar under running hot water for a few seconds, then try again. Then the lid opened easily. What is the MOST likely reason Manuel’s father suggested using hot water to loosen the lid?

• Glass contracts when it is heated.

• Metals expand when they are heated.

• Metals are easier to grip when they are warm

• Hot water reduces friction between metal and glass.

What causes your skin to feel warm when it is in the sun on a summer day?

• Particles in the atmosphere reflect energy from the Sun downward.

• Hot particles from the Sun still carry some heat when they reach your skin.

• The solar wind carries heated air from the Sun’s atmosphere to Earth’s surface.

• The Sun radiates energy that passes through space and the atmosphere to your skin.

People sitting around a campfire are able to feel the heat from the fire. How are the people able to feel the heat from the fire without touching the fire?

• The heat from the fire travels through the ground and heats the ground around the people.

• The heat from the fire is conducted through air molecules to the people.

• The heat from the fire rises in the air and then settles around the people.

• The heat from the fire radiates from the fire to the people.
