Multiple Choice

What would happen to a fully inflated balloon that is left in a car on a hot day?

• The air in the balloon will continue to expand and it might pop.

• The balloon will maintain its volume. It will not expand nor contract.

Multiple Choice

What is happening to the particles of gas inside the balloon under the sun?

• As heat is added, the particles move slower, which decreases the space between them, decreasing the volume.

• As heat is added, the particles move faster, which increases the space between them, increasing the volume.

​Particles During Contraction and Expansion

• Number of particles.

• Space between particles.

• Size of each particle.

• The volume that the particles take up.

Multiple Select

During expansion and contraction, ________ and _______ remain the same.

• number of particles

• space between particles

• size of each particle

• the volume that the particles take up

Multiple Select

​Learning Objective

Compare Between The Effects of High and Low Temperature on Gas Pressure.

​Vocabulary

• Pressure: the amount of force per unit area applied to an object's surface.

• Air pressure: the force caused by collisions of air particles around objects.

​Page 101

Fill in the Blank

____________ is caused by the collisions of air particles around objects.

Why does the liquid stay in the straw?

• When you place your finger on top of the straw, you reduce the air pressure on top of the liquid.

• The liquid stays in the straw because there is more air pressure acting on the bottom of the liquid than at the top.

​Page 101

How Gas Pressure is Measured?

​Gas pressure is measured by the number of collisions of the particles with the container.

• Pressure's unit is atmosphere (atm).

• The pressure at sea level is 1 atm.
