I have two balloons same size and are filled with the same amount of helium. Colors differ, one is black one is white. Which will rise faster on a sunny day?

..ur right. Dark colors absorbed more heat compared to light colors.

In this case the black balloon expand easily and does make it move faster up high.

During summer time, we wear most of the time a light colored dresses esp white..when u have these clothes on u feel cool rather than wearing dark colors.

keep up the good work!

Hi again,

U seem to be good at chemistry which I hate most among my subjects. I think the black will rise faster because black color absorbs all foton of light, so it gets greater energy which make volum of helium in the black balloon grow more and this volum make the back balloon reduse, so we have the result.

I hope that u will give me the exact answer.

Have a nice day,

Lalan
