Which of the following is an example of conduction?

A metal spoon becomes warm when placed in a cup of hot tea.

Once heat from the Sun penetrates the Earth's atmosphere, the heat is circulated as warm air rises and cold air sinks. What is this process called?

convection

When hot and cold air meet, the hot air rises to the top. Which process causes the hot air to rise?

convection

A transfer of heat within a liquid or gas that involves warm particles moving in currents is

convection.

The diagram below shows three solid objects. Two of the objects are hot and one is cold. If heat is transferred between these objects via conduction, use the arrows to indicate the direction or directions in which heat flows.

both arrows towards the cold

Heat energy is transferred by conduction whenever molecules

collide.

In which of the following methods of heat transfer is it necessary for the objects to be directly touching one another?

conduction

Tamara pours hot tea into a cold mug. A few moments later, she picks up the mug, and it is now warm.What is the main form of energy transfer involved in heating the mug?

conduction

Mildred takes a pound of frozen hamburger meat out of the freezer and puts it into the refrigerator.Which of the following best describes the direction of heat flow?

from the air in the refrigerator to the hamburger

A fan pushes hot air out of a vent and into a room. The hot air displaces cold air in the room, causing the cold air to move closer to the floor. The hot air displacing the cold air is an example of ___________transfer by __________

heat, convection

Which of the following is an example of convection?

hot air rising and cooler air falling

In the Earth's mantle, heat is transferred in large convection currents. Within these currents,

hotter rock rises and cooler rock sinks.

Mario brings his hands near a fire and feels its warmth. If the air around Mario's fireplace is still, most of the heat is reaching his hands through _______.

radiation

Through which of the following ways does the Sun primarily transfer its heat energy to the Earth?

radiation

The diagrams below represent three different types of heat transfer. Match each diagram to the type of heat transfer it represents.

radiation, conduction, convection

Plants obtain their energy from light produced by the Sun. Sunlight is transferred from the Sun to the plants through a process known as

radiation.

The light from the Sun heats a metal surface. This is an example of

radiation.
