    Need a bit of help:
    What does the second law of thermodynamics state? Why is it so fundamental?
    Like I sort of get it is to do with entropy and you can break even at 0 Kelvin. There are a bunch of entropy equations which come together to make the gibbs free energy. But ultimately I don't really get what it is saying.
    What does gibbs free energy value show?

    Also why is it that we can't convert all of heat into work , what is the reason for the inefficiency. The second law says something about 0 kelvin? Anyone care to explain that bit as well.

    Thanks
