Question 1

1.

Drag each answer choice into the correct space. Not all answer choices will be used. 

All objects that are made of ___________contain thermal energy because of the constant motion of their __________.  Objects with greater thermal energy also have more _________ than those with less thermal energy.  

Other Answer Choices:

matter

waves

heat

atoms

light

Question 2

2.

Drag each example to the type of heat transfer that it describes.

A pot of cold water is placed on a hot stove and gradually heats as hotter molecules move through the water.
An ice cube that is placed on a hot plate gradually melts, and the plate's temperature becomes cooler.
The sun transfers its thermal energy through electromagnetic waves and gradually heats the Earth's surface.

Conduction
Convection
Radiation

Question 3

3.

Which statements are true about conduction as a form of heat transfer? Select two correct answers.

When heat is conducted, it is transferred from one object to another until equilibrium is reached. 

Unlike other forms of heat transfer, conduction does not require a temperature difference between objects. 

If one object has a large amount of thermal energy and the other has less,  the one with more will transfer heat. 

Heat can be conducted through fluids such as liquids and gases, but it cannot be conducted through solids. 

All matter conducts heat equally well because all matter contains atoms that are constantly in motion.
