Chemistry Chapter 2: States of Matter

The reverse of condensation is

• sublimation

• freezing

• evaporation

• boiling

Boyle's Law explains the relationship between volume and pressure for a fixed amount of

• a gas

• a solid

• a liquid

• any type of matter

According to Charles's Law,

• crushing a closed container of gas will increase the pressure

• filling a balloon with helium will cause it to rise

• heating a balloon will cause it to expand

• pumping more air into a basketball will increase the pressure

Which of these factors could affect the temperature at which water boils?

• the volume of water in the pot

• the atmospheric pressure at which the water is heated

• the amount of energy added to the water

How do the particles of water that evaporate from an open container differ from the particles that remain?

• The evaporated particles only have more speed.

• The evaporated particles have greater order.

• The evaporated particles only have higher energy.

• The evaporated particles will have more speed and higher energy.

Which of the following occurs when liquid becomes a gas?

• The particles break away from one another.

• The particles move closer together.

• The particles slow down.

• The particles give off energy.

The melting point of salt is the same as its

• boiling point

• freezing point

A liter of water will boil at

• a higher temperature than a milliliter of water

• a lower temperature than a milliter of water

• the same temperature of a milliliter of water

If you open a bottle of perfume, after a period of time, the people on the opposite side of the room will be able to smell it due to the process of

• condensation

• vapor pressure

• evaporation

• sublimation

Gas has

• no definite volume

• a definite volume
