Understanding Boyle's Law

Which two properties of gases are involved in Boyle’s Law?

• Volume and Temperature

• Pressure and Temperature

• Volume and Pressure

• Mass and Density

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

• They are directly proportional.

• They are inversely proportional.

• They are unrelated.

• They are equal to each other.

According to Boyle’s Law, at constant temperature, what happens when the volume of a gas increases?

• The pressure increases.

• The pressure decreases.

• The temperature increases.

• The gas condenses into a liquid.

What is the correct equation for Boyle’s Law?

• 𝑃1𝑉1=𝑃2𝑉2

• 𝑉1/𝑇1=𝑉2/𝑇2

• 𝑃1/𝑇1=𝑃2/𝑇2

• 𝑃𝑉=𝑛𝑅𝑇

What does the Kinetic Molecular Theory (KMT) say about the movement of gas molecules?

• They move in slow, circular motions.

• They are fixed in place with strong attractions.

• They move randomly in straight-line motion.

• They slow down when colliding with the container.

A gas has a volume of 5.0 L at a pressure of 2.0 atm. If the pressure is doubled, what happens to the volume?

• It increases to 10.0 L.

• It decreases to 2.5 L.

• It remains at 5.0 L.

• It becomes zero.

What happens to gas molecules when the volume of a container decreases?

• They move faster and collide more often.

• They slow down and stop moving.

• They become attracted to each other.

• They escape the container.

Which real-life scenario best demonstrates Boyle’s Law?

• A balloon expanding when heated.

• A syringe pulling in liquid when the plunger is pulled back.

• Water turning into steam.

• A metal rod expanding due to heat.

If a gas occupies a volume of 8.0 L at 1.5 atm, what happens to the volume if the pressure is increased to 3.0 atm at constant temperature?

• 4.0 L

• 8.0 L

• 12.0 L

• 16.0 L

Which graph best represents Boyle’s Law?

• A straight line sloping upward

• A straight line sloping downward

• A downward-curving graph

• A horizontal line
