Answer : When the balloons filled with oxygen then the balloons will sink.
When the balloons filled with nitrogen then the balloons will float.
Explanation :
As we given that:
The density of air = 1.20 g/L
The density of nitrogen = 1.17 g/L
The density of oxygen = 1.33 g/L
- When the density of a substance will be greater than the density of medium then the substance will sink.
- When the density of a substance will be lesser than the density of medium then the substance will float.
Here, substance is nitrogen and oxygen and medium is air.
As per question we conclude that,
The density of substance (oxygen) is greater than the density of medium (air). That means, when the balloons filled with oxygen then the balloons will sink.
The density of substance (nitrogen) is less than the density of medium (air). That means, when the balloons filled with nitrogen then the balloons will float.
Hence, the correct option is, It would float.
