Gas Laws and Biomolecules Quiz

In Boyle’s Law, which factor remains unchanged?

• Mass of the gas

• Pressure

• Temperature

• Volume

According to Boyle’s Law, what is the relationship between the pressure and volume of a gas when temperature remains constant?

• Constant

• Directly Proportional

• Inversely Proportional

• Unrelated

Which gas behavior is explained by Boyle’s Law?

• Gas expands when heated

• Gas condenses when cooled

• Gas is compressed in a sealed container under pressure

• Gas molecules move faster when temperature increases

Which of the following real-life situations best demonstrates Boyle’s Law?

• Ice melting into water

• A hot air balloon rising into the sky

• A tire becoming warm after driving for a long time

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

If a scuba diver ascends too quickly, the gas in their lungs can expand and cause injury. This is an example of Boyle’s Law because:

• The oxygen in the tank is used up

• The diver exhales to balance the pressure

• The temperature increases as the diver moves up

• The water pressure decreases, allowing the gas volume to expand

Charles' Law is best represented by which equation?

• P1V1=P2V2

• V1T2=V2T1

• V1/T1=V2/T2

• P1/T1=P2/T2

According to Charles' Law, what happens to its volume when the temperature of a gas increases at constant pressure?

• Decreases

• Doubles

• Increases

• Remains the same

If the temperature of a gas is doubled (in Kelvin) while keeping the pressure constant, what happens to the volume?

• It doubles

• It is cut in half

• It remains the same

• It decreases by one-fourth

Why must the temperature in Charles' Law calculations be in Kelvin instead of Celsius?

• Kelvin is easier to use

• Celsius cannot be converted into volume

• Charles' Law only applies to high temperatures

• Kelvin starts from absolute zero, avoiding negative values

Which real-life scenario is an example of Charles' Law?

• A car tire deflating due to a puncture

• A submarine changing depth in water

• A gas cylinder exploding due to high-pressure

• A balloon shrinking when placed in a refrigerator
