# How will you distinguish between a hard boiled egg and a raw egg by spinning it on a table top?

## Why does a raw egg spin differently than a boiled egg?

The hard boiled egg spins for much longer (and faster) than the raw egg. This is because the inside is solid, so the entire thing is one solid mass. The raw egg has liquid on the inside, which is not attached to the shell. The liquid inside it much harder to spin, and it slows the egg down much faster.

## How can you tell if an egg is hard boiled without cracking it open?

A hard-boiled egg, being solid, will spin smoothly. A raw egg, being liquid inside, will wobble. Double-check by spinning the egg and suddenly stopping its rotation with the tip of your finger. A hard-boiled egg comes to an immediate stop and stays stopped if you lift your finger.

## How you distinguish a raw egg and boiled egg using law of conservation of angular momentum?

Both eggs are spinning on the top of the table, the fluid is thrown outward therefore, moment of inertia of fluid egg be greater than moment of inertia of boiled egg. conservation of angular momentum, when external torque be zero , angular momentum of system remains constant.
