Understanding Suction and Air Pressure

What was the initial object used to demonstrate the concept of a suction cup?

• A rubber mat

• An ice bucket lid

• A plastic sheet

• A metal plate

What is the average speed of air particles at room temperature?

• 700 meters per second

• 513 meters per second

• 1000 meters per second

• 300 meters per second

What is the force per unit area called?

• Mass

• Pressure

• Volume

• Density

What happens to the particles inside the suction cup when it is hit?

• They remain still

• They move in circles

• They get forced out

• They increase in size

What is the calculated weight pushing down on the suction cup due to air particle collisions?

• 500 pounds

• 935 pounds

• 200 pounds

• 1200 pounds

Why does suction not actually exist?

• Because the table is too smooth

• Because the suction cup is too light

• Because there is nothing pulling the suction cup

• Because there is no air pressure

What material property is crucial for a suction cup to function properly?

• Elasticity

• Rigidity

• Transparency

• Conductivity

What ensures that the collisions on the outside of a suction cup are not opposed by added collisions on the inside?

• The suction cup's shape

• The suction cup's color

• The suction cup's weight

• The suction cup's temperature

What is the role of long chain polymers in suction cups?

• They make the suction cup heavier

• They make the suction cup transparent

• They allow the suction cup to conduct electricity

• They enable the suction cup to stretch and maintain shape

How does the suction cup maintain its position on the table?

• By using magnets

• By creating a vacuum

• By increasing its weight

• By changing its color
