A solid is a state of matter that has a(n)

•  indefinite volume and an indefinite shape
•  definite volume and a definite shape
• definite volume and an indefinite shape
• indefinite volume and a definite shap

The resistance of a liquid to flowing is its

• pressure
• temperature
• viscosity
• volume

According to Boyle’s law, when the pressure of a gas increases at constant temperature, its volume

• increases
• stays constant
• decreases
• increase, then decreases

The greater the speed of gas particles in a container, the

• fewer collisions there will be
• lower the pressure
• greater the pressure
• lower the pressure

When the temperature of a gas decreases at constant volume, its

• pressure increases
• mass increases
• pressure decreases
• particles move faster

According to Charles’s law, when the temperature of a gas increases at constant pressure, its

• volume increases
• mass increases
• volume decreases
• particles move more slowly

When an inflated balloon is exposed to cold air,

• the air temperature inside the balloon rises
• the pressure inside the balloon rises.
• the volume of the balloon decreases
• the volume of the balloon increases.

The surface of water can act like a sort of skin due to a property of liquids called

• viscosity
• surface tension
• condensation
• evaporation

The freezing point of water is the same as its

• melting point
• boiling point
• sublimation
• evaporation point

The boiling point of a substance is affected by

• the mass of the substance
• the substance’s volume.
• the pressure of the air above the substance
• the amount of surface tension the substance has.
