Modeling Phase Changes

The transformation from one state of matter to another is called a

When a material changes from solid to liquid, the material is

• vaporizing

• melting

• condensing

• depositing

• sublimating

Changing from liquid to gas is called

• vaporization

• melting

• condensation

• sublimation

• deposition

Changing from gas to liquid is called

• vaporization

• melting

• condensation

• sublimation

• deposition

Some solids can change directly into gas through a process called

• melting

• vaporization

• condensation

• sublimation

• deposition

Going from gas to solid is called

• melting

• vaporization

• sublimation

• condensation

As a liquid is heated, the particles __________ vibrational and rotational energy

• lose

• gain

• break

• remain

Select all that apply.

The relative strength of intermolecular forces can be used to predict differences in bulk properties like:

• hydrogen bonds

• boiling point

• melting point

• dipole-dipole

True or False:

The strength of intermolecular forces is related to the type of force and the size and weight of the molecules.

• True

• False

Select all that apply.

In the process of evaporation,

• particles at the surface that have enough energy can escape the liquid and enter the gas phase.

• some of the molecules in a gas will have lower energy than the rest and can transition to the liquid phase

• it happens at the surface of liquids and its one type of vaporization

• increasing the temperature of a liquid results in more particles having enough energy to evaporate
