PS Unit 1 review Phases and gas laws

Gas laws involve what three variables?

• Solid Liquid Gas 
• Speed Velocity Acceleration 
• Elements Compounds Mixtures 
• Pressure Temperature Volume 

What will happen to the volume of a gas if the pressure increases, with constant temperature ?

• Increase
• Decrease
• Nothing
• Explosion!

If you increase the pressure, what will happen to the temperature, if volume is constant?

• Increase
• Decrease
• Stay the same
• It will Blow Up

If a balloon is cooled what will happen to the volume?

• Volume will increase
• Volume will decrease
• Volume will not change

What Is Matter?

• Anything That has weight and takes up space.
• Anything that you can see or taste.
• What you can touch.
• you and go throught this.

What Is Volume?
