WHY CANT MAN REACH 0K ( -273°C ) ?

WHAT WILL HAPPEN IF WE REACH 0K ?

Hi guys ! I hope u all have read a chapter call thermodynamics and I also hope u know something about equilibrium reactions........

In thermodynamics we have read that -273.15°C ( absolute zero ) is just a theoretical temperature....nobody can reach there.....

Have u ever wondered why ?

The reason behind this is at 0K all process become reversible process...but in nature there is no reversible proesss....

For example, consider a spring block system with all surfaces made of metal.....

Now if u start to oscillate it heat energy will be produced .....now if this process is called reversible reaction only when the reverse also happens ie, when the system is at rest and if u apply heat it must oscillate....is it happening..?

So reversible reactions aren't possible hence we cannot reach 0K
