increase in balloon size.
You blow up an air impermeable balloon at sea level, and then hike to the peaks in the Sierra Nevadas, Denali, Mt Everest, the Alps or Mt Kilamanjaro, and you notices the balloon’ s diameter has expanded. You also know that the temperature has dropped and the air pressure decreased as you ascended the heights. Develop a hypothesis and an experiment to determine whether pressure or temperature or both are responsible for the increase in balloon size.
………………….Answer preview………………….
An inflated impermeable balloon has air molecules colluding with the balloon’s wall and when subjected to high temperatures the balloon is likely to expand because the continuous and increased commotion of the particles within that balloon. The particles also expand and that’s why an inflated balloon’s diameter will be seen expanding, (Sun, Lim, Lee and Khoo, (2015). In our case here the inflated balloon was not subjected to high temperatures but instead was taken to very high altitudes where we expect the temperatures to be very low. Any object that is subjected to low temperatures is likely to contract but the balloon expanded. Therefore it is clear to say that the temperature in this case was not the reason why the balloon expanded……………………………………
