Question

A balloon has 0.6m3 of hydrogen at normal atmospheric pressure . At the same temperature if its volume is increased by 15 % , calculate the pressure surrounding the balloon ​

Answer 1

Answer:

As the balloon volume decreases, pressure inside the balloon increases. It eventually is able to balance the outside air pressure. You end up with a balloon filled with cold high density air. If you warm air it will expand and density will decrease until the pressure inside and outside the parcel are equal.
