Absolute entropy of a system, surroundings or the universe can never be negative because it isnвЂ™t possible to have negative disorder (this is due to the definition of entropy just remember that entropy can never be negative). The surroundings will compensate accordingly to keep the energy of universe constant and increaseВ the entropy.

The energy (in the form of enthalpy) and entropy can increase or decrease in a system. Note that these two statements are talking about the system, rather than the universe. Based on these two laws, we can determine that statement I and statement II are false. This suggests that the universe is always going towards a more disordered state. The second law of thermodynamics states that the entropy, or the amount of disorder in the universe, is always increasing. The energy lost by a system is gained by surroundings and vice versa however, the total energy of the universe is always constant.

It is also possible to use the free energy of Gibbs (О”G) and enthalpy (О”H) to find О”S.The first law of thermodynamics states that the energy of the universe is always constant, which implies that energy cannot be created or destroyed. ОЈО”S products refers to the sum of the О”S products,ДЄnd ОЈО”S reactants refers to the sum of the О”S reactantsДЈ. Where О”S rxn refers to the standard entropy values, If the process reaction is known, we can use a table of standard entropy values to find О”Srxn. When the process occurs at a constant temperature, the entropy would be:Дў. There are several equations to calculate the entropy:ДЎ. It contains the system entropy and the entropy of the surroundings.

Also, scientists have concluded that the process entropy would increase in a random process. The entropy of the solid (the particles are tightly packed) is more than the gas (particles are free to move). It is the thermodynamic function used to calculate the system's instability and disorder. While reversible adiabatic expansion is isentropic, it is not isentropic to irreversible adiabatic expansion. The process is defined as the quantity of heat generated during the entropy change and is reversibly divided by the absolute temperature.

It is defined by S but represented by SВ° in the regular state.

Entropy is the state function that depends on the system state.

The various properties of entropy are as follows: It is a thermodynamic property, such as temperature, pressure and volume, but we cannot visualize it easily. German physicist Rudolf Clausius was introduced entropy in 1850. The principle of entropy provides a fascinating insight into the course of random change in many daily phenomena. The amount of entropy is also a measure of the system's molecular randomness or disorder, as the work is generated from ordered molecular motion.

Entropy measures the system's thermal energy per unit temperature.
