Gases

At a constant pressure, the volume decreases.  What happens to the temperature?

• increases
• decreases
• stays the same

Pressure in gases is a measure of:

• the number of collisions per second of the particles with the side of the container.

• the force of the collisions of the particles with the side of the container.

• the amount of space taken up by the particles in the container.

• None of the above

The pressure inside the balloon will:

• Decrease

• Increase

• Remain the same

• Not enough information to formulate an answer

The pressure of the gas in the balloon in the ice water will be:

• Greater than that of the balloon in the boiling water.

• Less than that of the balloon in the boiling water.

• The same as that of the balloon in the boiling water.

• Not enough information to answer the statement.

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.

We can increase the pressure of a gas by:

• Adding more gas.

• Reduce the volume of the container.

• Increase the temperature of the gas.

• 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.
