What is the relative density rubber eraser?

Answer 1

The relative density of a rubber eraser refers to the ratio of the density of the eraser material to the density of water. Rubber erasers typically have a relative density close to 1, meaning they are very similar in density to water. This property allows rubber erasers to float in water, making them easy to retrieve if dropped into a liquid.

Answer 2

The relative density of a rubber eraser is typically around 1.1 to 1.3, which means it is slightly denser than water. This allows the eraser to effectively remove pencil marks from paper without leaving residue or tearing the paper.

Answer 3

Oh, dude, the relative density of a rubber eraser is basically how much denser it is compared to water. So, if you drop a rubber eraser in water and it sinks, it's denser than water. If it floats, it's less dense. It's like a little science party in your pencil case, man.

Answer 4

Ah, the relative density of a rubber eraser is simply a measure of how dense it is compared to water. You see, if the relative density is less than 1, it means the eraser will float in water. If it's more than 1, it will sink. It's just a fun way to understand how objects interact with water.
