Answer 2

Liquid

Question 3

A substance with no definite volume and no definite shape is known as a

Answer 3

Gas

Question 4

A substance with a definite volume and a definite shape is known as a

Answer 4

Solid

Question 5

What is thermal energy?

Answer 5

Heat

Question 6

Does “a phase change” have the same meaning as “a change in the state of matter”?

Answer 6

Yes, a phase change from a solid to a liquid has the same meaning as a solid changing its state of matter to a liquid.

Question 7

When thermal energy increases in a substance, what will happen to kinetic energy, temperature, and particle movement?

Answer 7

They will all increase. A pot of water heating on the stove. The temperature increases as the kinetic energy increases causing the particles in the water to move faster.

Question 8

What will happen to a solid if thermal energy is added to it?

Answer 8

It will heat up and change from a solid phase to a liquid phase. Particles will loosen up and begin to slide over each other.

Question 9

What will happen to a liquid if thermal energy is added to it?

Answer 9

It will heat up and change from a liquid phase to a gas phase. Particles will spread further and further apart getting more and more excited and bouncing off of each other.

Question 10

What will happen to a gas if thermal energy is added to it?

Answer 10

The particles will become more excited, move farther apart and stay a gas.
