What is density?

Back

Density is the mass of a substance divided by its volume, typically expressed in g/cm³.

Front

What is a heterogeneous mixture?

Back

A heterogeneous mixture is a mixture in which the components are not uniformly distributed and can be easily distinguished.

Front

What is a homogeneous mixture?

Back

A homogeneous mixture is a mixture in which the components are uniformly distributed and cannot be easily distinguished.

How does density affect whether an object will float or sink in a liquid?

Back

An object will float in a liquid if its density is less than the density of the liquid; it will sink if its density is greater.

Front

What happens to a solid with a density of 2.7 g/cm³ when placed in a liquid with a density of 3 g/cm³?

Back

The solid will float if its density is less than the liquid's density.

Front

What is the formula for calculating density?

Back

Density = Mass / Volume.

Front

What is the significance of the density of liquids W, X, Y, and Z in the context of the quiz?

Back

The density of the liquids determines whether the solid quartz will pass through them or float.

What is the relationship between mass and volume in determining density?

Back

Density is directly related to mass and inversely related to volume; as mass increases, density increases if volume remains constant.

What is an example of a homogeneous mixture?

Back

An example of a homogeneous mixture is saltwater.
