Science 10

Which of the following BEST describes Boyle's Law?

• The volume of a gas is directly proportional to its pressure

• The volume of a gas is inversely proportional to its pressure at constant temperature

• The temperature of a gas is directly proportional to its pressure

• The pressure of a gas increases as temperature increases

If the pressure on a gas doubles, what happens to its volume (assuming constant temperature)?

• The volume doubles

• The volume remains the same

• The volume decreases by half

• The volume increases by four times

When deep-sea diving, why do air bubbles get larger as they rise to the surface?

• The temperature increases

• The pressure increases

• The pressure decreases

• The air molecules multiply
