Then, they add 5 ml of water to the canister and quickly close it. It does not store any personal data. Physical changes can be observed with the naked eye, and they do not result in a change to the chemical composition of the substance. Physical changes include transitions from one state to another, such as from solid to liquid or liquid to gas. The ripening process will change the peel from being thick and stiff to thin and more flexible, with brown spots surfacing until the entire peel darkens. He also shares personal stories and insights from his own journey as a scientist and researcher.
