Reacted | Boiling water | 100mL | Balloon expanded | Cooled water | 100mL | Balloon contracted‚ fell into beaker | Labelled Diagram: Analysis and Conclusion Based on my date that I have found I can conclude that my hypothesis is correct. That if the temperature of a balloon is raised‚ then it will expand. If the temperature of the balloon is lowered‚ then the balloon will contract. The data that I found is a follows: If a balloon is placed on a beaker with 100mL of boiling water‚ the balloon
