Question

Take a small quantity of solution A and solution B in a jar. Density of A is 2 kg/m3 and density of B is 5 kg/m3. Which of these float above the jar? Give reason?

Answer 1

Answer:

The solution A will float above the solution B

Explanation:

The most important rule for buoyancy is that,

the rarer liquid will always float

the denser liquid will always sink

Rarer liquid or solution is the liquid or solution having lesser density

Denser liquid is the liquid having more density

In the given question,

Density of A = 2 kg/m³

Density of B = 5 kg/m³

Therefore, in the given question

A is the rarer liquid

B is the denser liquid

Hence,

A will float over B and

B will sink under A
