Gas Laws Test

When a basketball is left outside in the cold it goes flat because the volume of air inside the ball has been reduced. What  gas law does this represent?

• Boyle's Law

• Charles's Law

A gas occupies 3.5 L at 1.2 atm of pressure. What volume does it occupy at 2.4 atm pressure?

• 1.75 L

Gas laws involve what three variables?

• Solid Liquid Gas 

• Speed Velocity Acceleration 

• Elements Compounds Mixtures 

• Pressure Temperature Volume

• Flask 1

• Flask 2

• Flask 3

• Flask 4

The pressure in an automobile tire is 2.3 atm at 27°C. At the end of a journey on a hot, sunny day the pressure has risen to 2.6 atm. What is the temp of the air in the time assuming the volume has not changed?
