Calculating Boyle's Law Problems

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 is held constant. This means that as the volume increases, the pressure decreases, and vice versa.

Front

What is the formula for Boyle's Law?

Back

The formula for Boyle's Law is P1 * V1 = P2 * V2, where P1 and V1 are the initial pressure and volume, and P2 and V2 are the final pressure and volume.

Front

If the initial pressure is 59 ATM and the final pressure is 28 ATM, how do you find the initial volume if the final volume is 26 L?

Back

Use Boyle's Law: P1 * V1 = P2 * V2. Rearranging gives V1 = (P2 * V2) / P1. Plug in the values: V1 = (28 ATM * 26 L) / 59 ATM = 12.34 L.

Front

How does increasing the volume of a gas affect its pressure according to Boyle's Law?

Back

Increasing the volume of a gas decreases its pressure, assuming the temperature remains constant.

Front

What happens to the volume of a gas if its pressure is doubled while keeping the temperature constant?

Back

If the pressure of a gas is doubled, its volume is halved, according to Boyle's Law.

Front

If a gas has an initial volume of 70 L and a final volume of 19 L, how do you calculate the final pressure if the initial pressure is 57 ATM?

Back

Use Boyle's Law: P2 = (P1 * V1) / V2. Plug in the values: P2 = (57 ATM * 70 L) / 19 L = 210 ATM.

Front

What is the relationship between pressure and volume in a closed system?

Back

In a closed system, pressure and volume are inversely related; as one increases, the other decreases.

Front

If a gas has a final volume of 95 L and a final pressure of 53 ATM, how do you find the initial pressure if the initial volume is 66 L?

Back

Use Boyle's Law: P1 = (P2 * V2) / V1. Plug in the values: P1 = (53 ATM * 66 L) / 95 L = 76.29 ATM.

Front

What is the significance of temperature in Boyle's Law?

Back

Temperature must remain constant for Boyle's Law to apply; if temperature changes, the relationship between pressure and volume will also change.

Front

If the initial pressure is 55 ATM and the final pressure is 56 ATM, how do you find the initial volume if the final volume is 35 L?

Back

Use Boyle's Law: V1 = (P2 * V2) / P1. Plug in the values: V1 = (56 ATM * 35 L) / 55 ATM = 35.64 L.
