Gas exit ticket

In what direction(s) does air exert pressure?

• In all directions

• In no direction

• there is no pressure

Which container will have a lower pressure?

• left
• right
• they both have the same pressure

When the temperature of matter increases the particles...

• speed up and move closer
• speed up and move farther apart
• slow down and move closer together
• slow down and move farther apart

What is the difference between particles in a gas and a solid?

• gas particles are closer together
• solid particles move faster than gas particles
• solid particles expand on heating
• gas particles have more kinetic energy than solid particles

The pressure inside the balloon will:

• Decrease

• Increase

• Remain the same

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.

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.

TRUE or FALSE: In order to change the state of matter, you need increase or decrease the energy (heat).

• TRUE

• FALSE

When changing a substance from liquid to gas, the energy has to...

• INCREASE

• DECREASE

Look at the picture. Which state of matter is in beaker C?

• Solid

• Liquid

• Gas
