Physical Properties of Matter Review 5.6A 5.6B 5.6C

Front

What is a physical property of matter?

Back

A characteristic of a substance that can be observed or measured without changing its identity, such as color, density, mass, and volume.

Front

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

Back

It means that the substance can transfer heat through it, allowing it to warm up or cool down.

Front

What is density?

Back

Density is the mass of a substance divided by its volume, often expressed in grams per cubic centimeter (g/cm³).

Front

How can you determine if an object is a metal?

Back

By testing if it conducts thermal energy; metals typically conduct heat well.

Front

What happens to the properties of a substance when it dissolves in water?

Back

Some properties, like taste or color, may remain, but others, like texture, may change.

Front

What is the relationship between density and buoyancy?

Back

An object will float in a fluid if it is less dense than the fluid; it will sink if it is more dense.

Front

What is an example of a substance that is less dense than water?

Back

Cooking oil is less dense than water, which is why it floats on top.

Front

What is the significance of the term 'solubility'?

Back

Solubility refers to the ability of a substance to dissolve in a solvent, such as sugar dissolving in water.

Front

What is a mixture?

Back

A combination of two or more substances that retain their individual properties and can be separated by physical means.

Front

What is the difference between a solution and a mixture?

Back

A solution is a homogeneous mixture where one substance is dissolved in another, while a mixture can be heterogeneous and retain the properties of its components.
