Topic 2 Solid, Liquid, Gases

A substance that has neither a definite shape or a definite volume is a

• fluid

• solid

• liquid

• gas

In a solid, particles do not move around each other, but they do

• change shape

• vibrate

• flow

• sit completly still.

Sugar is considered a crystalline solid because its particles are

• arranged in a regular pattern.

• arranged randomly.

• completely motionless.

• able to move aroudn one another.

Vaporization that takes place both above and below the surface is called

• evaporation

• boiling

• condensation

• precipitation

When the gas pressure above a liquid increases, the amount of thermal energy required for the liquid to vaporize

• increases

• decreases

• stays constant

• becomes zero.

When the temperature of a gas decreases, and volume is held constant, the pressure of the gas

• increases

• decreases

• stays the same

• becomes zero

Adding thermal energy to a gas at constant pressure will cause

• the volume of the gas to decrease.

• the volume of the gas to increase.

• the temperature of the gas to decrease.

• the pressure of the gas to decrease.

Orange juice

• has a surface tension that is different from gasoline.

• changes volume when poured into a different container.

• has the same viscosity as other liquids.

• has a definite shape.

Boyle’s law explains the relationship between volume and pressure for

• a small amount of a gas

• a large amount of a liquid.

• a fixed amount of a gas.

• a fixed amount of a liquid.

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

• the size and shape of the pot in which the water is heated

• the atmospheric pressure at which the water is heated

• the amount of heat added to the water

• the temperature of the water before it is heated
