Storyboard Description
reversable and irrevarsable changes
Texte du Storyboard
Oh no!We had to use this iron for costruction, but it has started to rust
And it is an irrevesible change.
This shovel is very handy for soil digging, we need more of them. Do you know how it is made?
Yes, I do. The iron blade is fixed to the wooden handle by the proccess of expansion on heating , it is a reversible change
Uh oh!No electricity, we'll have to manage with candles
Do you know, melting of wax is reversible change and burning of wax is an irreversible change.
