8.3 Measuring Matter

Front

What is mass?

Back

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

Front

What is the SI unit of mass?

Back

The SI unit of mass is the kilogram (kg).

Front

What happens to the mass of an object when it is moved to a different location?

Back

The mass of an object remains the same regardless of its location.

Front

What is density?

Back

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

Front

What is the relationship between density and floating?

Back

An object will float in water if its density is less than 1 g/mL.

Front

What are the four measurable properties of matter?

Back

The four measurable properties of matter are mass, weight, volume, and density.

Front

What is weight?

Back

Weight is the force exerted by gravity on an object, often measured in newtons (N).

Front

How does gravity affect weight?

Back

Weight changes with the strength of the gravitational pull; it is greater on planets with stronger gravity.

Front

What is volume?

Back

Volume is the amount of space an object occupies, typically measured in liters (L) or cubic centimeters (cm³).

Front

How do you calculate density?

Back

Density is calculated by dividing mass by volume (Density = Mass/Volume).
