How can you fit a giraffe, 2 dogs and a swan into a standard laboratory beaker?!

·         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
