Why does a hard boiled egg spin faster than a raw one?

Which has greater moment of inertia boiled egg or raw egg?

Actually raw egg has higher moment of inertia. It’s due to its distribution of mass. Boiled egg rotates slower as it loses kinetic energy due to more amount of mass need to rotated but for raw egg more amount of mass is concentrated at centre leaving less mass at surface.

Did the cooked egg stop moving once you let it go how about the raw egg?

The hard-cooked egg will remain stationary, but the raw egg will start spinning again. That’s because the liquid inside didn’t stop moving when you stopped the shell.

Do hard boiled eggs keep spinning?

What did the hard boiled egg do when you lift your finger?

The raw egg keeps spinning after you touch it briefly because the liquid egg inside remains in motion, it’s inertia is greater than that of the solid interior of the hardboiled egg. An object’s momentum is its resistance to changing its state of motion; roughly “how hard it is to stop”.

What is the green in the over cooked hard boiled egg?

A: The green ring around the yolk of a hard cooked egg happens because hydrogen in the egg white combines with sulfur in the yolk. The cause is most often related to boiling the eggs too hard for too long. The green ring can also be caused by a high amount of iron in the cooking water.
