· How can you fit a giraffe, 2 dogs and a swan into a standard laboratory beaker?! 5.13 Starter 2 02 November 2011 18:17
· Use particle theory to explain why the gas in the balloon contracts Explanation
· The temperature of the gas inside the balloon decreases so the average speed of the particles decreases
· Consequently the gas particles collide with the walls of the balloon with less force and less collisions per second
· Because the walls of the container are flexible, the volume decreases 5.13 Charles' law 28 October 2011 11:10
· 5.13 understand that there is an absolute zero of temperature which is –273oC
> Open the Charles' law interactive experiment
· Adjust the temperature
· What’s the relationship between temperature and volume?
· Plot a graph of V against T
· Take a screen shot of the graph 5.13 results and conclusion 28 October 2011 11:10

Conclusion
· Volume is directly proportional to absolute (Kelvin) temperature
· V α T
