Laws

The three laws involved in Geothermal plants - Three of the four laws of thermodynamics.

1.         The 0th law - Temperature: if system A is in thermal equipoise with another system C, and a thermodynamic system B is also in thermal equilibrium with C, then A and B atomic number 18 in thermal equilibrium. This applies even if A and B are separated by an adiabatic barrier (one through which NO heat sack flow)

2.         The 1st law - Energy is conserved. It stooget be created or destroyed, scarcely transformed into different types of energy.

3.         The 2nd law - heat does not of itself flow from a cold object to a intense object.

Basic Intro

A geothermal plant is a plant that sits on devolve of a hot water reservoir (at least 182º Celsius) with an guess and production well, as seen in this diagram. (from http://www.eere.energy.gov). It produces electricity by powering massive turbines that are connected to electrical generators.

The complex stuff

Deep to a turn down place the earths surface, in the mantle, there is water that is heated by the press and heat near the earths core. Although the core can reach temperatures round 5000º Celsius, the water under the Earths crust is anywhere between 50º and 350º.



In reservoirs where the temperature is at or above 182º, geothermal plants are often in place to produce electricity, with steam daunt techniques.

As the heated water is extracted from the earth it is extracted into much cooler temperatures and lower pressure. In the high pressure underneath the ground, the water can be up to 300º, yet doesnt evaporate into steam? Why? Because when the water is underground, the pressure from the surrounding environment simoleons the bubbles of molecules from separating into individual...
