Boyle's Law

Front

What is Boyle's Law?

Back

Boyle's Law states that the pressure of a gas is inversely proportional to its volume when the temperature and amount of gas are held constant.

Front

What is the formula for Boyle's Law?

Back

The formula for Boyle's Law is P₁V₁ = P₂V₂.

Front

If the pressure of a gas increases, what happens to its volume?

Back

If the pressure of a gas increases, its volume decreases, provided the temperature and amount of gas remain constant.

Front

What happens to the pressure of a gas if its volume is halved?

Back

If the volume of a gas is halved, the pressure will double, assuming temperature and amount of gas are constant.

Front

What are the units of pressure commonly used in Boyle's Law?

Back

Common units of pressure include atmospheres (atm), millimeters of mercury (mm Hg), and pascals (Pa).

Front

What is the relationship between pressure and volume in Boyle's Law?

Back

The relationship is inversely proportional; as one increases, the other decreases.

Front

What must be held constant for Boyle's Law to apply?

Back

Temperature and the amount of gas (moles) must be held constant.

Front

Calculate the new volume of a gas if the initial volume is 350 L and the pressure decreases from 720 mm Hg to 600 mm Hg.

Back

The new volume is 420 L.

Front

If a gas occupies 4.98 L at 2.6 atm, what volume does it occupy at 1.8 atm?

Back

The volume at 1.8 atm is 7.2 L.

Front

What happens to the pressure of a gas when its volume decreases?

Back

When the volume decreases, the pressure must increase.
