The second principle of termodynamics says:
cooler object cannot give away heat spontaneously to warmer one.
I wonder then how do cooler and wormer object appear in a closed system after they have equalized their heat.Or in other words:
Is there a way back <=> Could this phenomenon be reversible in a closed system?
Billioners don't appear in the middle of desert but in the center of society.
