Question 24

What is heat?

Answer 24

The movement of thermal energy from a region of higher temperature to a region of lower temperature(hot to cold, hot to cold)

Question 25

What is temperature?

Answer 25

Represents the average kinetic energy of the particles that make up a material

Question 26

What is conduction?

Answer 26

The transfer of thermal energy due to collisions between particles in matter

Question 27

What is convection?

Answer 27

The transfer of thermal energy by the movement of particles from one part of a material to another

Question 28

Which material moves, thermal energy, slowly, a thermal insulator, or a thermal conductor

Answer 28

A thermal insulator moves, thermal energy more slowly

Question 29

What is radiation?

Answer 29

The transfer of thermal energy from one object to another by electromagnetic waves

Question 30

What is thermal expansion?

Answer 30

The increase in the volume of a material when it’s temperature increases is known as thermal expansion

Question 31

What is thermal contraction?

Answer 31

The decrease in the volume of a material when it’s temperature decreases

Question 32

How does a thermometer work?

Answer 32

A thermometer has a red liquid inside, and the wet liquid is put in cold water. It decreases and when it’s put in hot water, it increases.

Question 33

What are the three temperature scales?

Answer 33

Kelvin , Fahrenheit , and Celsius

Question 34

What is the difference between melting and freezing?

Answer 34

When something is melting the material changes from a solid to a liquid, but when it is freezing, it changes from a liquid to a solid

Question 35

What is vaporization and what are the two ways that it occurs?

Answer 35

Vaporization is the change in state from a liquid to a gas. The two ways that vaporization occurs are boiling and evaporation.

Question 36

What is condensation?

Answer 36

The change of state from a liquid to a gas

Question 37

What is sublimation?

Answer 37

The change of state that occurs when a solid changes to a gas without passing through the liquid state

Question 38

What is deposition?

Answer 38

The change of state for a gas directly to a solid without passing through the liquid state
