Question

Is it possible to predict physical or chemical changes? I don't really understand how to predict a change from the information my science teacher is giving me. The textbooks say what physical and chemical changes are but not how that means we can predict them.

Answer 1

Explanation:

It is possible to predict a physical change or chemical change because they have very unique properties and differences.

A physical change is a change that alters the physical properties of matter especially form and state.

A chemical change is a change in which new kinds of matter is formed.

Here are some of the properties and indicators of the these change;

• A physical change is easily reversible
• Chemical changes are not easily reversible

• Physical changes leads to the production of no new kind of matter.
• Chemical change produces new kinds of matter

• Physical change involves no change in mass
• Chemical change involves a change in mass

• Physical change requires little to no amount of energy
• Chemical change requires considerable amount of energy.
