Q

physical changes in matter

A
  1. Are changes that are reversible
  2. No new substance is formed
  3. New properties may appear, but the particles of the starting substance(s) are not changed.
  4. It may change form or state
18
Q

example of a physical change in matter

A

Ice melting

The new properties of the ice are temporary, because a change of state can be reversed.

The liquid water can be changed back into ice.

19
Q

Chemical changes in matter

A
  1. Are changes that are irreversible
  2. A new substance with new properties will be formed
20
Q

example of chemical changes in matter

A

Burnt toast

When a piece of bread is burnt, it forms a layer of charcoal on the front and back of the piece of toast. - A new substance with new properties is formed
The burnt toast cannot be turned back into bread.
