5.6A Physical Properties STAAR

Front

What are physical properties?

Back

Physical properties are characteristics of a substance that can be observed or measured without changing the substance's identity, such as color, density, mass, volume, and state of matter.

What does it mean for a material to conduct thermal energy?

Back

A material that conducts thermal energy allows heat to pass through it easily. Metals like copper and aluminum are good conductors of thermal energy.

Front

What does it mean for a material to conduct electrical energy?

Back

A material that conducts electrical energy allows electric current to flow through it easily. Metals like copper and aluminum are good conductors of electricity.

Front

What is density?

Back

Density is the mass of a substance divided by its volume. It determines whether an object will float or sink in a fluid.

Front

What happens to objects with a density less than water?

Back

Objects with a density less than water will float on the surface.

Front

What happens to objects with a density greater than water?

Back

Objects with a density greater than water will sink to the bottom.

Front

What is solubility?

Back

Solubility is the ability of a substance to dissolve in a solvent, such as water.

Front

What does it mean for a material to be soluble in water?

Back

A material that is soluble in water can dissolve in water to form a solution.

Front

What is an insulator?

Back

An insulator is a material that does not conduct heat or electricity well, such as rubber or plastic.

Front

What is the difference between a conductor and an insulator?

Back

A conductor allows heat or electricity to flow through it easily, while an insulator resists the flow of heat or electricity.
