Why is it a physical change when ice melts to liquid water?
Melting ice is a physical change because the properties of the physical changes say that there is a physical change when the state of a material changes. the ice changes into water after melting .this is temporary change as the property says. you can change water back into ice by freezing.
Is the melting of plastic a chemical reation?
