Thermodynamics

There are three laws of thermodynamics. These laws focus on the inter-relation between heat, work and the internal energy of a system. In other words, it is the study of energy conversion in the form of heat . Thermodynamics focus on three major factors that affect energy conversion. These factors are: pressure, volume and temperature.

The 3 Laws

1)You cannot win

This law discusses the conservation of energy. Simply, it states that energy be created or destroyed. The sum of mass and energy is always conserved


2)You cannot break even

This law discusses the direction of the conservation. It states that energy cannot return to its original state because there is always an increase in entropy (disorder). According to physicist, Lord Kelvin, "usable energy in the universe is becoming less and less. Ultimately there would be no available energy left." Although quantity remains the same (First Law), the quality deteriorates over time. Accordingly because usable energy is used for productivity, growth or repair, it is converted into unusable energy. As usable energy decreases and unusable energy increases, "entropy" increases.



3) You cannot get out of the game

The third law refers to a state known as absolute zero. This is the lowest point on the Kelvin temperature scale. which corresponds to about -273.15° Celsius. This law reasons that no object or system can have a temperature of zero Kelvin.
