Why is it impossible to have a tempertaure value below 0 K ?

Question

Why is it impossible to have a tempertaure value below 0 K ?

Answer 1

10 raise to power -4(?) is the maximum lowest so far achieved. On 0K the molecules theoretically would cease to move which is impossible(may be possible after some decades).

Thnx.

Answer 2

0 K means MINIMUM POSSIBLE ENERGY...so molecuoules will stop moving and no more energy can possibly be taken away from them...

0 K is -273 degrees celcius

Answer 3

0 K is absolute zero. the point where the molecules of any substance stop moving. If the molecules have stopped moving by then then it would be  impossible to get it any colder

Answer 4

Absolute zero is the point at which molecules do not move.  It is a theoretical limit and cannot be achieved.

Answer 5

Because 0 k is when atoms stop moving so you can't go past that.

Answer 6

anything below 0k would not exist

it would have a negative energy

Answer 7

Because 0 K is ABSOLUTE ZERO.  It is the total absence of any energy whatsoever.  Even ice has a shred of heat in it.  

Think of it this way:  technically, there is no such thing as "cold."  Only heat.  And the measurement of heat starts at zero K and moves up from there.
