Law of thermodynamics

3rd law
As a system approaches the temperature of absolute zero (0 Kelvin), all movement ceases and the entropy of the system approaches a minimum value.
A temperatures drop, the energy of the atoms decreases as it increases entropy.
As temperature increases, atomic activity increases, which generates more heat.
As temperature decreases, atomic activity decreases, which generates less heat.
2nd law
The entropy of an isolated system that is not in equilibrium will tend to increase over time, approaching a maximum value at equilibrium.
Entropy is a measure of the unavailability of a system's energy to do work. In the centralization that a process is reversible, the entropy does not change, while irreversible processes always increase the total entropy.
2nd law means
A process can only occur in an isolated system if it increases the total entropy of the system. It reduces the availability of system's energy to do work.
Heat can not spontaneously flow from a material at a low temperature to a material at a higher temperature.
It is not possible to convert heat completely into work. Some of the heat energy must be passed on to the heat sink (material at a lower temperature).
1st law
The law of conservation: energy may not be created or destroyed. However, energy may be changed from one form to another.
Friction turns kinetic energy into thermal energy, which creates heat.
Energy dispersal
Energy dispersal occurs when concentrated energy is dispersed (transferred) over time, resulting in a reduction of the energy available to do work.
This also results in pressure, temperature, and density balancing out in the system. The system is moving toward maximum entropy as pressure, temperature and density balance with it.
Absolute zero
As the temperature nears absolute zero, the individual atoms quit moving.
