Distinguish between the first law of thermodynamics and the second law of thermodynamics?

Answer 1

The first law of thermodynamics is a generalized axiom of nature in relation to the conservation of energy. The most common enunciation of first law of thermodynamics is:

The increase in the internal energy of a thermodynamic system is equal to the amount of heat energy added to the system minus the work done by the system on the surroundings.



The second law of thermodynamics is a axiom of nature regarding the directional flow of heat in relation to work and which accounts for the phenomenon of irreversibility in thermodynamic systems. The most common enunciation of second law of thermodynamics is:

Heat cannot of itself pass from a colder to a hotter body.

This is equivalent to this scientific statement:

The entropy of an isolated system not at equilibrium will tend to increase over time, approaching a maximum value.

The second law is most applicable to macroscopic systems. For example, when one part of an isolated system interacts with another part, energy will tend to distribute equally among the accessible energy states of the system. As a result, given time, the system will reach a state of thermodynamic equilibrium, at which point the entropy will have a maximum value and the deviation of free energy will be greater than or equal to zero.

0. If two systems are in thermal equilibrium with a third system, then they must be in thermal equilibrium with each other.
1. , where dE is the energy change, is the change in heat, dW is the work done, T is the temperature, dS is the change in entropy, P is the pressure, and dV is the volume change.
2. The second law of thermodynamics prohibits the construction of a perpetual motion machine of `the second kind.' A consequence is the result that .
3. As temperature goes to 0, the entropy S approaches a constant .
