1.  They measure the tempature by telling how fast the paritcles in the air are moving.  So if it was a hot tempature that would mean that the particles are moving really fast.
2.  Well the Kelvin and Celsius ones both measure in the same degrees between the freezing and boiling points but they have different zero points which make them very alike and different. One intervel of Fahrenheit is equal to about 5/9 of Celsius which shows how they are different. "Unlike the degree Fahrenheit and degree Celsius, the kelvin is not referred to or typeset as a degree."  This was said by http://en.wikipedia.org/wiki/Kelvin.  And this basically means that Kelvin isn't really a degree such as Celsuis and Fahrenheit.
