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.
I believe the answer is A (it was on another Brainly question as well).
