Entropy [entropy] and Chiu Pi [HEAT DEATH]

What is entropy? What is heat death?

Before answering this question, we must first ask "why is the temperature from high to low".

Molecules tend to flow to places with low energy, which should be well understood, like current resistance, like you will take a road without traffic jams.

Conservation of energy, all flows consume energy, no matter what form of energy (heat, light, electricity...). The exchange of energy is not equivalent, and different energy has different efficiencies when converting, and the work will become weaker and weaker...

Therefore, entropy is used to describe this phenomenon: in a closed system, without the influence of external forces and other factors, the energy will be lower and lower, the entropy will be higher and higher, from order to disorder and chaos.

And this also extends a very interesting idea - heat death

"When all the energy in the universe is exhausted, all the planets are dead."

 Don't you think it's very romantic, the universe is lonely after all.
