10-3 Fill in the Blanks

BLANK is a gas changing directly into a solid. (reverse process of sublimation.)

deposition

Dissolving can be reversed with BLANK.

evaporation

When a substance dissolves, it mixes BLANK.

evenly

When adding thermal energy added to a solid, the particles move BLANK and BLANK, temperature increases, overcome attractive forces that hold them tightly together, and reaches the melting point.(solid changes to the liquid.)

faster

When adding thermal energy added to a liquid, the particles move faster, temperature BLANK, overcome attractive forces, and reaches boiling point.(liquid to gas.)

increases

The BLANK in physical changes do not become new substances.

matter

To change the state of matter, the movement of the BLANK has to change.

particles

A BLANK BLANK is a change in size, shape, form, or state of matter in which the matter's identity stays the same.

physical change

Dissolving is a BLANK BLANK because the identities of the substances are not changed.

physical change

Changes in BLANK and size are physical changes are physical changes.

shape

When thermal energy is removed from a gas, the particles move more BLANK, temperature decreases, attractive forces pull the particles close together, and condensation occurs. (gas to liquid.)

slowly

Sublimation is when a BLANK changing to a gas.

solid

Changes in shape and size do not result in a new BLANK.

substance

To change the movement of particles, BLANK BLANK must be either added or removed.

thermal energy

When thermal energy is removed from a liquid, the particles move more slowly, temperature decreases, BLANK forces pull the particles tightly together, and freezing occurs. (liquid to solid.)

attractive

Boiling point and BLANK are reverse processes and occur at the same temperature.

condensation

The BLANK BLANK BLANK is the total mass before and after a physical change and a chemical change is the same.

conservation of mass

Most physical changes are BLANK to reverse.

easy

When you rip a paper in half, it changes in size and shape, but it is still BLANK. It went through a physical change.

paper

The BLANK in matter that are present before a physical change are the same as those present after the physical change.

particles

Freezing and melting point are reverse BLANK and occur at the same temperature.
