![]() ![]() ![]() In simpler words, entropy gives us an idea about that portion of energy that does not convert into work done and adds to the disorder of the system instead. the more is the spontaneity in a thermodynamic process, the higher is its entropy or the degree of disorder. It helps redefine the second law of thermodynamics.Įntropy relates to spontaneity i.e. Entropy is an interesting concept as it challenges the belief of complete heat transfer. The entropy is denoted by ‘S’ and it is an extensive property because the value of entropy or Entropy Change is dependent on the substance present in a thermodynamic system. The term disorder denotes the irregularity or lack of uniformity of a thermodynamic system. This randomness could be in regards to the entire universe or a simple chemical reaction or something as simple as the heat exchange and heat transfer. So, let's understand this concept of entropy and the change in entropy.Įntropy is the measure of disorder or randomness. By this law, the entropy of the universe can never be negative. The second law of thermodynamics talks about the concept of entropy and tells that the entropy of the universe is always increasing. Three laws govern the science of thermodynamics and here we will discuss the second law of thermodynamics. It also deals with the work done for the conversion of energy from one form to another. ![]() Thermodynamics is the study of the changes in energy associated with the change in temperature and heat. ![]()
