When something is magnetized, all of the atoms are facing a different direction. When you drop it/throw it/hit it with enough force, it causes the atoms to spin, so they are not all facing the same way.
Ionizing radiation, for example X-rays, gamma rays and alpha particles
There are called the stomata
I believe it would be water boils at 100 Celsius to Fahrenheit, Celsius to Fahrenheit, kelvins.
