Let’s firstly understand “how cold is cold”
Absolute Zero is -237o C!
There is heat energy in everything above -237o C.
There is heat energy in snow and ice!
There is heat energy in the wind and rain.
Now let’s understand “how does heat energy transfer”
Touching steals heat….
Fridges & freezers steal heat ….
Thermodynamics systems works like a fridge in reverse.
The system simply extracts free sustainable heat energy from the air, the sun, the rain, the wind, and even snow!
Simply put…..Thermodynamics is the transfer of heat energy.
