Question

At 20 degrees Celsius, the density of air is 1.20 g/L. Nitrogen's density is 1.17 g/L. Oxygen's density is 1.33 g/L. Will balloons filled with oxygen rise or sink in the air? Will balloons filled with nitrogen rise or sink in the air? Why? (3 points)

Answer 1

balloons filled with oxygen will sink and balloons filled with nitrogen will also sink, this is because oxygen is more dense than air but nitrogen is only slightly less dense than air meaning it is not enough for the nitrogen to rise

Answer 2

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.
