Density Comparison

Front

What is density?

Back

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

How do you determine if an object will float or sink 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 than that of water.

Front

What does it mean for an object to be more compact?

Back

An object is more compact if its particles are closely packed together, resulting in a higher density.

Front

What does it mean for an object to be less compact?

Back

An object is less compact if its particles are spread out, resulting in a lower density.

Front

If two objects have the same mass but different volumes, how do their densities compare?

Back

The object with the smaller volume will have a higher density.

Front

What is the formula for calculating density?

Back

Density = Mass / Volume.

Front

If an object has a density of 0.8 g/mL, will it float or sink in water?

Back

It will float, as its density is less 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

How can you compare the densities of two liquids?

Back

You can compare the densities by observing which liquid floats on top of the other; the less dense liquid will float.

Front

What happens to the density of a substance when it is heated?

Back

Generally, the density decreases when a substance is heated, as its volume increases.
