What adding energy (heat) to dry ice what happens?

Answer 1

it sublimates --- ie goes straight from a solid to a gas --- and i would suggest dont add too much heat as the gas will expand very quickly ---- have fun

Answer 2

do you mean when?
Well dry ice is basically solidified carbon di oxide so it starts to change its state and vaporizes quickly. It goes from solid to vapour giving a sort of white fog around it. Hence it is used in smoke machines. When energy is added to a system the molecules gain energy and move apart and when molecules are too far apart to mantain a fixed solid shape they change state.

Answer 3

When energy is added to dry ice by heating, the molecules becomes more energetic, causing it to sublime.

Answer 4

fog
