Answer:
good question pr mujhe nhi samajh aaya
Explanation:
Materials:
2 water bottles
8 ounces white vinegar
4 tablespoons baking soda
Bowl
Ice water
2 balloons
Permanent marker
Small funnel
Timer
Procedure:
Mark your two balloons with permanent marker:"1" for room temperature, "2" for ice bath.
Mark the water bottles the same way:"1" for room temperature, "2" for ice bath.
Use the small funnel to put 2 tablespoons of baking soda in each balloon.
Clean the funnel well with running water, then dry it.
Use the small funnel to put 4 ounces of white vinegar in each water bottle.
Place Bottle 2 in the bowl of ice.
After three minutes place the balloon on top of the bottles, being careful not to spill the baking soda into the bottles yet.
Set your timer.
Tip both balloons upwards to drop the baking soda into the vinegar.
Record your results.
Results:
Baking soda and vinegar should have been able to blow up the ballon every time. However, you should have observed that the balloon at room temperature blew up significantly faster than the cold balloon.
Why?
When vinegar and baking soda mix, they create the gas carbon dioxide and water. The carbon dioxide has no where to go, but into the balloon - blowing it up. But you should have found that the balloon at room temperature may have been slightly faster in blowing up your balloon. This is because the colder temperature causes the reaction to take place more slowly, releasing the gas less effectively.
With science, the learning never stops; you can always change an experiment a little bit and get a completely different result! What if you used hot water instead of an ice bath? What if you used lemon juice instead of vinegar? What if you changed the size of the balloons? Whatever you do, make sure you only make one change at a time and leave all other factors the same...then conduct your experiment and record your results!
