HLEP NOW 5TH GRADE SCIENCE What is the main difference between a chemical and Physical change? Use examples to support your answer.

Physical change

When a substance undergoes a physical change, its composition remains the same despite its molecules being rearranged.

Physical change is a temporary change.

Physical change is a temporary change.

A physical change involves very little to no absorption of energy.

Generally, physical changes do not involve the production of energy.

In a physical change, no new substance is formed.

Physical change is easily reversible i.e original substance can be recovered.

Some examples of physical change are freezing of water, melting of wax, boiling of water, etc.

Chemical change

When a substance undergoes a chemical change, its molecular composition is changed entirely. Thus, chemical changes involve the formation of new substances.

A chemical change is a permanent change.

Chemical change both physical and chemical properties of the substance including its composition

During a chemical reaction, absorption and evolution of energy take place.

Chemical changes usually involve the production of energy (which can be in the form of heat, light, sound, etc.)

A chemical change is always accompanied by one or more new substance(s).

Chemical changes are irreversible i.e. original substance cannot be recovered.

A few examples of chemical change are digestion of food, burning of coal, rusting, etc.

The financial planning has roughly the same structure. Even in their later stages of life, they need to prepare and pre-save for any major risks that may occur. Having a spouse and children may increase this risk as well. It’s important to set aside a little future college money for their kids, maybe an allowance, ect. Their savings when it comes to risk management should also be increased. Having to not only prepare for accidents with themselves, they now also have to prepare for any accidents including their children and spouse. Saving money for assets is also important, going in debt would put the whole family in danger so making sure house/apartment payments, car payments, taxes, ect., is needed.
