Question

A metal cylinder is melted and the whole mass is cast in the shape of a cube. What happens to its density? Give reason ​

Answer 1

The density in both the cases will be same because the mass remains the same and the volume of the water displaced by the metal cylinder and the cube remains the same.

Answer 2

Answer:

>>>Density is constant for given substance or material.

So, when it is cast into different shapes, the density of the material remains same as before.

Density is defined as the mass of the substance per unit volume.

Density = Volume/Mass

Mass of the metal cylinder and that of the cube will be same when measured via spring balance experiment.

Mass of water displaced in both cases doesn't change.

Similarly, volume of the water displaced in the measuring unit of the spring balance remains same in both the scenario.So, density remains same.
