Density Flashcardzi Practice 1

Front

What is density?

Back

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

Front

What is the formula for calculating density?

Back

Density = Mass / Volume

Front

What is the density of water?

Back

1 g/mL

Front

How does density affect whether an object floats or sinks in water?

Back

An object will float if its density is less than that of water (1 g/mL) and sink if its density is greater.

Front

What can you infer if two liquids have the same volume but different weights?

Back

The liquid that weighs more has a higher density.

Front

What instrument is used to measure the volume of an irregularly shaped object?

Back

Graduated cylinder.

Front

True or False: The density of a substance can help identify it, such as distinguishing gold from other metals.

Back

True.

Front

If a substance has a density of 2 g/mL, will it float or sink in water?

Back

It will sink because its density is greater than that of water.

Front

What happens to the density of most substances when they are heated?

Back

Most substances decrease in density when heated, as they expand.

Front

What is the relationship between mass and volume in terms of density?

Back

Density is directly proportional to mass and inversely proportional to volume.
