Mr. Metcalf Atoms and the Properties of Matter.

What is density?

Back

Density is the mass of an object divided by its volume, often expressed in grams per milliliter (g/mL) or kilograms per cubic meter (kg/m³).

Front

How do you determine which of two objects with the same volume is more dense?

Back

The object with the greater mass is more dense.

Front

What happens to an object with a density less than that of water when placed in water?

Back

It will float.

Front

What is matter?

Back

Matter is anything that has mass and takes up space.

Front

What is a mixture?

Back

A mixture is a combination of two or more substances that are not chemically bonded together.

Front

What is the relationship between mass and density?

Back

Density is calculated by dividing mass by volume; therefore, for a given volume, greater mass results in higher density.

Front

If an object has a density of 1.0 g/mL, what will happen if it is placed in water?

Back

It will neither sink nor float; it will remain suspended.

Front

What is the formula for calculating density?

Back

Density = Mass / Volume.

Front

What is the difference between a pure substance and a mixture?

Back

A pure substance has a uniform and definite composition, while a mixture contains two or more substances that retain their individual properties.

Front

What is the significance of the density of an object in real-world applications?

Back

Density helps determine whether an object will float or sink in a fluid, which is important in fields like engineering and environmental science.
