Density

Front

What is density?

Back

Density is defined as mass per unit volume, typically expressed in grams per milliliter (g/mL) or kilograms per cubic meter (kg/m³).

How do you determine if an object will sink or float in water?

Back

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

Front

What is the formula for calculating density?

Back

Density = Mass / Volume.

Front

If two objects have the same volume but different masses, which one is more dense?

Back

The object with the greater mass is more dense.

Front

Where is the most dense material found inside the Earth?

Back

The most dense material is found at the center of the Earth.

Front

What happens to an object with a density of 0.6 g/mL when placed in water?

Back

It will float because its density is less than that of water.

Front

What happens to an object with a density of 3.6 g/mL when placed in water?

Back

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

Front

What is the relationship between density and buoyancy?

Back

Buoyancy is the ability of an object to float in a fluid, which is determined by the object's density relative to the fluid's density.

Front

What is the density of water at standard temperature and pressure?

Back

The density of water is approximately 1 g/mL at standard temperature and pressure.

Front

How does temperature affect the density of a substance?

Back

Generally, as temperature increases, the density of a substance decreases because the substance expands.
