Revolt · Accepted Answer

freezing and condensation

Question 3

During which change of state would the volume of a substance increase the most?

Revolt · Accepted Answer

sublimation

Question 4

Which is the process by which a solid changes to a liquid?

Revolt · Accepted Answer

melting

Question 5

A cylinder at left has balls stacked near its bottom with an arrow leading to a cylinder at right with balls evenly spaced throughout the cylinder.

Revolt · Accepted Answer

sublimation

Question 6

What happens if atoms lose energy during a change of state?

Revolt · Accepted Answer

The atoms are pulled together by attractive forces and become more organized.

Question 7

As atoms gain energy, they move faster and slide past one another more easily. Atoms at the surface of the substance overcome attractions to nearby atoms and break free of the surface.

Revolt · Accepted Answer

liquid to gas

Question 8

A cylinder at left with balls stacked near the bottom of the cylinder has an arrow leading to a cylinder at right cylinder with balls in a layer on the bottom of the cylinder.

Revolt · Accepted Answer

Atoms gain energy as a solid changes to a liquid.

Question 9

A cylinder at left with balls evenly spaced throughout the cylinder has an arrow leading to a cylinder at right cylinder with balls stacked near its bottom.

Revolt · Accepted Answer

Atoms lose energy as a gas changes to a solid.

Question 10
