Hypothesis: If we increase the temperature of the water, hen the balloon will expand. If we decrease the temperature of the water, then the balloon will contract. Materials and Procedures: Manipulated Variable: water temperature Responding Variable: volume of the balloon Controlled Variables: chemical amount, pressure, materials Materials: * See other page Proceed rest: Observations: Charles’ Law Balloon/Water Lab Date Table Water Temperature I Water Amount How Balloon Reacted I Boiling water 1 moll I Balloon expanded I
Cooled water 1 moll I Balloon contracted, fell into beaker I Labeled Diagram: Analysis and Conclusion Based on my date that I have found 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 moll of boiling water, the balloon will gain volume and expand.
If the water in the beaker under the balloon is cooled, then the balloon will lose volume and contract. Potential sources of error in this lab were: experiment was conducted once rather than three times, water in the sink was not cold enough, water in the beaker was not hot enough, lack of a working.
