Front

What is a property of metals?

Back

Metals are malleable, meaning they can be shaped or bent without breaking.

Front

What is evidence of a physical change?

Back

A shape change is evidence of a physical change.

Front

What are boiling point, melting point, and density classified as?

Back

They are classified as physical properties of an element.

Front

How do you calculate density?

Back

Density = Mass / Volume.

Front

What is the pH of a basic substance compared to an acidic substance?

Back

A substance that is more basic has a higher pH than a substance that is acidic.

Front

Define malleability in metals.

Back

Malleability is the ability of a metal to be deformed or shaped under compressive stress.

Front

What is the difference between physical and chemical properties?

Back

Physical properties can be observed without changing the substance, while chemical properties involve a change in the substance's composition.

Front

What happens to the shape of a substance during a physical change?

Back

The shape of a substance can change, but its chemical composition remains the same.

Front

What is the significance of boiling point in physical properties?

Back

The boiling point is the temperature at which a substance changes from a liquid to a gas.

Front

What does a higher pH indicate about a substance?

Back

A higher pH indicates that the substance is more basic.
