Density with Floating and Sinking

Front

What is density?

Back

Density is the mass of an object divided by its volume, usually expressed in grams per cubic centimeter (g/cm³) or grams per milliliter (g/ml).

Front

What is the formula to calculate density?

Back

Density = Mass / Volume

Front

What happens to an object with a density less than 1 g/cm³ when placed in water?

Back

It will float.

Front

What happens to an object with a density greater than 1 g/cm³ when placed in water?

Back

It will sink.

Front

If an object has a mass of 30g and a volume of 10cm³, what is its density?

Back

3 g/cm³

Front

What unit is commonly used to express density?

Back

g/cm³ or g/ml

Why does a brick sink in water while a wooden block floats?

Back

The brick has a higher density than the wooden block.

Front

What is the density of water?

Back

1 g/cm³

Front

If two objects have the same volume but different masses, which one has a higher density?

Back

The object with the greater mass has a higher density.

Front

How does temperature affect the density of liquids?

Back

Generally, as temperature increases, the density of liquids decreases.
