Thermodynamics earth system

Thermodynamics is a term used to describe the set of natural laws that govern the transfer of energy from one body to another. Thermodynamics (comes from Greek “therme”, heat and dynamics, power) control behaviour of energy as it moves in and out of the Earth system, and among its reservoirs.

Watt (W)

Watt (W) is the rate of energy transfer equivalent to 1 ampere under an electrical pressure of 1 volt. One watt equals 1/746 horsepower or 1 joule per second. It is the product of voltage and amperage (current).
