Carbonated drinks in cans have a small amount of space above the liquid level inside the can known as the "headspace." What would be true about the gas in this headspace if the can is opened?

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.

Temperature stays constant
