How weight is the decreasing and increasing again ?🤔 comments and share your friends....

How is the weight decreasing amd increasing again___Initially_ the tissue paper loses mass as it burns and gases are released. However_ the remaining ash_ being porous and lightweight_ can easily absorb moisture from the air. This absorbed moisture adds to the weight of the ash. Thus_ when you measure the weight of the ash after the tissue paper has burned_ it may weigh more than expected due to the water content it has absorbed post-combustion. #chemistry #science #physics #chemistrylab #scienceexperiment #laboratry #youtubeshort#youtube #science
