The pressure inside the syringe will decrease if we move the plunger in:

• Direction A

• Direction B

• We don't have to move the plunger as the pressure will change on its own.

• None of the above answers.

Weather balloons travel to a great height gathering data before the balloon bursts. This is because the atmospheric pressure (layer of gas surrounding the earth):

• Increases the higher you travel.

• Decreases the higher you travel.

• Remains the same.

• Not enough information to answer the question.

The reason gases can be compressed is because:

• The particles are very close together.

• The particles are merely vibrating.

• The particles are unable to move.

• The particles are very far apart.
