As far as i am concerned, temperature is (caused by) molecule movement.Even at 0'C, there is some molecule movement. So what is the minimum value the temperature can go?
(i have heard it is about -290, though i am not sure it is true...)

I believe you are referring to 0' kelvin which is -273.15' C. It is also the point in which all mollecular movement stops. I don't beleive that anyone has been able to prove this. There are a lot of theories about what would happen if you could chill somthing to 0 kelvin

The derivation of absolute zero takes place in first semester chemistry labs.

More sophisticated experiments have gotten temperatures down into the nanokelvins - a few billionths of a degree above absolute zero - and so far even the most bizarre predictions of quantum theory have been shown to occur, including the formation of an Einstein-Bose Condensate, which is now routinely produced and studied.

The third law of thermodynamics states that zero is unattainable.

We will never get to absolute zero.

Unless you can figure out how to break a scientific law....which is about as effective as throwing a rock in a pond and telling it not to splash.

0 Kelvin = -273 Celsius or:
0 Rankine = -460 Fahrenheit.

I'm sure everyone knows, but just for the record, this is not oogie boogie.
