This view of the second law of thermodynamics is very popular, and it has been misused. Some argue that the second law of thermodynamics means that a system can never become more orderly. This is untrue. It just means that to become more orderly (for entropy to decrease), you must transf...
In the framework of this hypothesis I can calculate the entropy production for an ecosystem under anthropogenic stress.By considering systems far from thermodynamic equilibrium, we can prove that the so-called exergy is a functional of a dissipative function, which is undertaken along the trajectory ...
How to calculate entropy change? Use the thermochemical equation shown below to determine the enthalpy for this reaction: 2 H2O(g) + 2 Cl2(g) rightarrow 4 HCl(g) + O2(g) Information: (i) COCl2(g) + H2O(l) rightarrow CH2Cl2(l) + O2(g) Delta H = 19 kJ (ii) H2O(g) rightarr...
To determine the density of a solid that has regular side lengths, it is first needed to calculate the volume of the solid using the equation volume = length x width x height. Once the volume is calculated, the mass can be found on a scale and the calculation of density can be complete...
information. The term information entropy was borrowed by Shannon from thermodynamics. The thermal entropy in thermodynamics is a physical quantity that expresses the degree of disorder of the molecular state. Shannon uses the concept of information entropy to describe the uncertainty of the information...
N6-methyladenosine (m6A) is a post-transcriptional modification that controls gene expression by recruiting proteins to RNA sites. The modification also slows biochemical processes through mechanisms that are not understood. Using temperature-dependent (

How to calculate the energy change in the reaction N_2(g) + 3H_2(g) rightarrow 2NH_3(g)? What is the relationship between a compound's stability and its enthalpy of formation? How to measure energy What's the difference between heat of reaction and heat of formation?
The third law of thermodynamics states the entropy of a perfect crystal at absolute zero is exactly equal to zero. Explore the definition of absolute entropy and how the third law of thermodynamics applies to absolute entropy in this lesson. Re...
The second law of thermodynamics says that the entropy of any isolated system always increases. The law implies that energy is naturally transferred from hotter to cooler bodies until equilibrium is reached. In simple terms, you suggest that your partner share their level of hotness with you for...
