5. U7 Mini Practical #4 Charles Law (variation of) & Can Crushing
Aim: Investigate the relationship between Gas (air) temperature and volume by ‘Crushing a Can”
Equipment & Method:
Results & Observation:
Enquiry:
Any difference in using a narrow/long can or a wider/short can?
What must occur for a the can to be ‘well and truly’ crushed?
Conclusion: Explain the Physics…
Charles Law assumed Volume is directly proportional to Temperature. Is Charles Law being followed in this Can Crushing activity?

6. U7 Mini Practical #5 Boyle's Gas Law: Marshmallow Under Pressure
Aim: Relate this demonstration to the definition of Boyle's Law – with constant Temperature, Pressure is inversely proportional to Volume
Equipment & Method:
Results & observation:
What happened to the marshmallow when you pushed in the plunger?
What happened when the plunger was pulled out?
Conclusion: How did this demonstration verify the accuracy of that law?
