I've read some where, ,that heat can go up to millions of degrees. But cold can drop just up to certain degree, witch is 275C if i am not mistaken?

it's -273 degrees Celcius, called absolute zero, it's -400 something Farenheit and 0 Kelvin, this is called absolute zero and it's the point at which all molecular activity stops, the reason cold has a certain point at which it stops is that there is no such thing as cold, what we call cold is just a lack of heat, so you can always add more heat, but there's only so much you can take away, however you can't add cold because it doesn't exist, so, since heat is a quantifiable material there must be a point at which there is none. Mind you, absolute zero is only theoretical, as of yet we cannot obtain it because in order to make something colder you need something else colder than the material you're cooling (I know that it's ironic saying there's no such thing as cold and then telling you to make something colder, get over it) and there's nothing colder than abolsute zero, in fact there may be nothing AS cold as absolute zero, because they'd reach an equilibrium that's above absolute zero then wouldn't cool.

The lowest temperature is when molecular motion stops. Once it stops, it can't go any slower so that is the temperature of "Absolute Zero". On the high end, there is no limit to how fast molecules (or at least atomic particles) can go. Above certain temperatures, the electrons get separated and the substance becomes a plasma which is what happens inside a neon sign.
Its like the earth, the lowest you can go is down to the center but there isn't a maximum distance (unless the universe stops expanding).

Type absolute zero into your search box. Long story short , to reach absolute zero all atomic activity would have to stop. No more electrons spinning around. I would not want to be around when that happened. Happy hunting.

At absolute zero atoms cease to be active.

there comes a point when atoms just stop moving so it cant freeze anymore
