Diagnostic Test- Chemistry- Boyle's Law

What does Boyle’s Law state about the relationship between the pressure and volume of a gas at constant temperature?

• Pressure and volume are directly proportional.

• Pressure and volume are inversely proportional.

• Pressure and volume are unrelated.

• 1. Pressure remains constant regardless of volume changes.

Which of the following represents the mathematical expression for Boyle’s Law?

• P_1​V₁​=P₂​V₂​

• P_1​+V_1​=P₂​+V₂

• PV=nRT

• P₁​/V_1​=P₂​/V₂​

If the pressure on a gas is doubled, what happens to its volume, assuming constant temperature?

• The volume doubles.

• The volume is halved.

• The volume remains the same.

• The volume decreases to one-fourth.

A gas has a volume of 4.0 L at a pressure of 2.0 atm. If the pressure increases to 4.0 atm, what is the new volume of the gas (temperature constant)?

• 1.0 L

• 2.0 L

• 3.0 L

• 8.0 L

In a syringe, when the plunger is pushed down, what happens to the pressure and volume of the air inside the syringe?

• Pressure decreases, and volume increases.

• Pressure increases, and volume decreases.

• Both pressure and volume increase.

• Both pressure and volume decrease.

Which of the following real-life scenarios is an example of Boyle’s Law?

• A soda can releasing gas when opened.

• A diver ascending too quickly and experiencing decompression sickness.

• Water boiling to form steam.

• 6. A car engine combusting fuel.

A gas is compressed from a volume of 6.0 L to 3.0 L while keeping the temperature constant. How does the pressure change?

• The pressure is halved.

• The pressure doubles.

• The pressure remains constant.

• The pressure decreases to one-fourth.

Which condition must remain constant for Boyle’s Law to apply?

• Temperature

• Volume

• Pressure

• Mass

What will happen to a balloon taken from the surface to the bottom of a swimming pool?

• The balloon’s volume will increase due to higher pressure.

• The balloon’s volume will decrease due to higher pressure.

• The balloon’s pressure will decrease as it goes deeper.

• 9. The balloon’s temperature will increase.

A gas occupies 10.0 L at 1.0 atm. What would be its volume if the pressure is changed to 2.0 atm (temperature constant)?

• 5.0 L

• 10.0 L

• 20.0 L

• 1.0 L
