Exploring Gas Laws Through Demonstrations

What does Avogadro's Law state about the relationship between gas volume and moles?

• There is no relationship between volume and the number of moles.

• Volume is inversely proportional to the number of moles.

• Volume is directly proportional to the number of moles.

• Volume decreases as the number of moles increases.

What is the volume of one mole of gas at standard temperature and pressure?

• 11.2 liters

• 22.4 liters

• 5.6 liters

• 44.8 liters

What happens to the volume of gas when the pressure is decreased, according to Boyle's Law?

• The volume decreases.

• The volume increases.

• The volume remains constant.

• The volume first decreases, then increases.

What happens to the volume of the balloons when the air is removed from the bell jar?

• It first increases, then decreases.

• It increases.

• It remains the same.

• It decreases.

How can Boyle's Law explain the increase in size of marshmallows under reduced pressure?

• The air inside the marshmallows expands as pressure decreases.

• The marshmallows absorb moisture from the air, causing them to swell.

• The chemical composition of marshmallows changes under reduced pressure.

• Reduced pressure causes the marshmallows to heat up and expand.

How does decreasing the pressure affect the air inside the marshmallows?

• It causes the marshmallows to freeze.

• It makes the marshmallows shrink.

• It has no effect on the marshmallows.

• It causes the marshmallows to expand.

What is the purpose of using a vacuum in the demonstration with suction cups?

• To show how a vacuum can generate electrical energy.

• To illustrate the force exerted by atmospheric pressure.

• To prove that vacuums can alter the chemical properties of materials.

• To demonstrate the effect of zero gravity on objects.

What gas law could be applied to explain the hard-boiled egg experiment?

• Both Charles' Law and Boyle's Law

• Boyle's Law

• Charles' Law

• Avogadro's Law

What principle explains the expansion of soap in a microwave?

• Avogadro's Law

• Boyle's Law

• Dalton's Law

• Charles' Law

Why do the soap pieces become light and fluffy when microwaved?

• The microwave radiation breaks down the soap's chemical bonds.

• The soap undergoes a phase change from solid to gas.

• The heat causes the air bubbles within the soap to expand.

• The soap absorbs water from the air, causing it to swell.
