Physical Behavior of Matter Vocabulary

The change from liquid to gas, which can occur through boiling or evaporation, is called:

• evaporation

• vaporization

• condensation

• sublimation

According to Charles' Law, the volume of a gas increases as the temperature increases.

• It increases

• It decreases

• It remains constant

• It first increases then decreases

What is the formula for kinetic energy?

• KE = ½mv² (where m is mass and v is velocity)

• KE = mgh (where m is mass, g is the acceleration due to gravity, and h is height)

• KE = mv² (omitting the ½ factor)

• KE = ½mv (incorrect representation with velocity not squared)

What is an exothermic process?

• A process that absorbs heat energy from the surroundings.

• A process that releases heat energy to the surroundings.

• A process that remains constant in temperature.

• A process that changes phase.

The change from solid to liquid is called:

• Melting

• Freezing

• Sublimation

• Condensation

Intermolecular Forces of Attraction are forces that attract molecules together.

• They are forces that attract molecules together.

• They are forces that repel molecules.

• They are chemical bonds within a molecule.

• They are intense nuclear forces.

A substance with definite shape and volume, where particles are tightly packed in fixed positions, is called:

• Liquid

• Gas

• Solid

• Plasma

The change from liquid to solid is called

• Freezing

• Melting

• Vaporization

• Condensation

The standard conditions for temperature and pressure (STP) are:

• 0°C and 1 atm

• 273.15K and 1 atm

• 25°C and 100 kPa

• 273.15K and 101.325 kPa

The measure of the average kinetic energy of particles in a substance is called:

• Temperature

• Pressure

• Volume

• Density
