The kinetic energy of the molecules in the system increases when we provide heat to the system,thereby increasing its temperature under certain conditions.

Similarly providing heat to a liquid increases the kinetic energy of liquid molecules and hence it's entropy to an extent.

But at the Big Bang the temperature is infinitely very much,so will be the kinetic energies of the molecules at that time,but at the Big Bang the universe is said to be in a state of high order.Is there any relation between kinetic energy and entropy?
