Understanding Charles's Law with Liquid Nitrogen

What is the main principle of Charles's Law?

• Volume and temperature are inversely proportional.

• Pressure and volume are inversely proportional.

• Temperature and volume are directly proportional.

• Pressure and temperature are directly proportional.

Which of the following is NOT required for the experiment?

• A metal bowl or Pyrex beaker

• A variety of balloons

• Liquid nitrogen

• Regular glass

What happens to the balloon when it is submerged in liquid nitrogen?

• It bursts due to pressure.

• It remains unchanged.

• It shrinks and then expands back to its original size.

• It expands immediately.

What is the state of nitrogen in the metal bowl during the experiment?

• Plasma

• Liquid

• Gas

• Solid

What causes the balloon to return to its original size after being removed from the liquid nitrogen?

• The balloon absorbs energy from the environment, increasing the temperature and volume of the air inside.

• The balloon is placed in a vacuum.

• The balloon is heated with a flame.

• The balloon is filled with more air.
