Why does a balloon deflate when taken outside on a cold day?

• The pressure inside the balloon increases

• The air inside the balloon loses thermal energy

• The air particles inside the balloon move faster

• The balloon absorbs moisture from the air

How does a change in pressure affect the state of matter of a substance, such as water?

• Increased pressure can cause water to freeze at a higher temperature

• Decreased pressure makes water boil at a lower temperature

• Increased pressure causes water to evaporate faster

• Pressure has no effect on states of matter

Why is air pressure important for evaporation to occur?

• It slows down evaporation

• Particles must overcome air pressure to evaporate

• It causes water to freeze

• Air pressure keeps particles from moving

What happens to the boiling point of a liquid when the pressure on its surface increases?

• The boiling point decreases

• The boiling point stays the same

• The boiling point increases

• The boiling point disappears

Fill in the blank: Boyle's law states that if the volume of a gas decreases, the pressure __________ (increases/decreases) if temperature remains constant.

How does adding more gas particles into a container affect the pressure inside the container?

• It decreases the pressure

• It has no effect on pressure

• It increases the pressure

• It increases volume, but pressure stays the same

Which of the following is an example of thermal contraction?

• A balloon expanding when heated

• Water freezing into ice

• A balloon shrinking in the cold

• A liquid evaporating into gas
