Measuring density is very important for many different industries because the density measurement will help determine the characteristics of a material, for example, whether the material will float or sink. Knowing the density of a material helps in determining the mass and volume of a material, all of which are extremely important measurements in all industries.

Answer:
Carbonated drinks in cans have a headspace to avoid explosion
Explanation:
- When we see in carbonated drinks in cans we can see there is a small amount of space above the liquid level known as the headspace. This space is not a wasted space. The gas filled in the can is compressed highly which when opened comes out with a high pressure with an explosion.
- Therefore, to avoid the carbonated drinks not to explode when shaken the carbonated drinks and the bottled juices have headspace. This means the headspace is not wasted.
