Charles' Law and Its Application

Charles' Law states that as the temperature increases, the volume __________.

• decreases

• increases

• is negligible

• remains the same

What material did Jacques Charles used to observe the relationship between the volume and temperature?

• Balloon

• Piston

• Tank

• Tire

Which of the following equation best describes Charles' Law?

• 
• 
• 
• 

Which of the following images show the application of Charles' Law?

• 
• 
• 
• 

In the virtual simulating activity, which factor becomes the dependent variable in the line graph?

• Height

• Length

• Volume

• Width

Which of the following does NOT describe the behavior of gas molecules under colder temperature?

• Gas molecules have slower rate.

• Gas molecules has less wall collisions.

• Gas molecules have to contract.

• Gas molecules move in narrower spaces.

Heating makes the the gas molecules move faster, why is this so?

• Because of the available space.

• Because it triggers the molecules.

• Because of frequent collisions.

• Because they gain kinetic energy.

Consider the formula at the left. How does Charles' Law keep the pressure constant if KMT states that the wall collisions of the molecules result in increased pressure inside the container?

• The volume of the container keeps up with the increasing pressure when the temperature rises.

• The volume of the container keeps up with the decreasing temperature when the pressure rises.

• The temperature of the container keeps up with the increasing pressure when the volume increases.

• The temperature of the container keeps up with the decreasing volume when the pressure increases.

Why do bibingka expand after it was baked over a charcoal?

• Because plenty of eggs are used in the mixture.

• Because the melted butter was absorbed by the mixture.

• Because of the large amount of glutinous rice flour in the mixture.

• Because heat and moisture activate the release of carbon dioxide from the baking powder.

Suppose Luna submerged a balloon in a cold water tub whose temperature is half of the room temperature. What will happen to its volume if pressure is kept constant?

• It will double.

• It will remain.

• It will be halved.

• None of the above.
