Physical Properties of Matter

Front

What are the physical properties of matter?

Back

Physical properties of matter are characteristics that can be observed or measured without changing the substance's chemical identity. Examples include color, shape, size, mass, volume, density, and state (solid, liquid, gas).

Front

Define mass.

Back

Mass is a measure of the amount of matter in an object, typically measured in grams or kilograms.

Front

What is volume?

Back

Volume is the amount of space that an object occupies, usually measured in liters or cubic centimeters.

Front

Explain density.

Back

Density is the mass of an object divided by its volume. It is a measure of how much matter is packed into a given space.

Front

What is the difference between a solid, liquid, and gas?

Back

Solids have a definite shape and volume, liquids have a definite volume but take the shape of their container, and gases have neither a definite shape nor volume.

Front

What is a physical change?

Back

A physical change is a change that affects one or more physical properties of a substance without altering its chemical composition. Examples include melting, freezing, and dissolving.

Front

What is a chemical property?

Back

A chemical property describes a substance's ability to undergo a specific chemical change, such as flammability or reactivity with acids.

Front

Give an example of a physical change.

Back

An example of a physical change is ice melting into water.

Front

What is the state of matter?

Back

The state of matter refers to the distinct forms that different phases of matter take on, primarily solid, liquid, gas, and plasma.

Front

What happens to the particles in a solid?

Back

In a solid, particles are closely packed together and vibrate in place, giving the solid a definite shape and volume.
