   8 hours ago · Entropy is a concept from thermodynamics that refers to the measure of disorder or randomness in a system. In simple terms, it explains how things naturally move from order to disorder. The second law of thermodynamics tells us that in any closed system, entropy will either stay the same or increase over time—it never decreases on its own.

   Oct 3, 2024 · In this activity, students observe various chemical and physical processes to qualitatively predict and explain the signs of ∆S and ∆H. Based on their observations, they will predict the sign of ∆G and will determine the driving force of the process. Students will then calculate ∆S, ∆H and ∆G. This lesson focuses on thermochemical ...

   What is entropy in physics?

   • Entropy is a scientific concept that is most commonly associated with a state of disorder, randomness, or uncertainty. The term and the concept are used in diverse fields, from classical thermodynamics, where it was first recognized, to the microscopic description of nature in statistical physics, and to the principles of information theory.

   What is specific entropy in chemistry?

   • Specific entropy may be expressed relative to a unit of mass, typically the kilogram (unit: J⋅kg −1 ⋅K −1). Alternatively, in chemistry, it is also referred to one mole of substance, in which case it is called the molar entropy with a unit of J⋅mol −1 ⋅K −1.

   Why is entropy important?

   • The most general interpretation of entropy is as a measure of the extent of uncertainty about a system. The equilibrium state of a system maximizes the entropy because it does not reflect all information about the initial conditions, except for the conserved variables.

   What is entropy state function?

   • When viewed in terms of information theory, the entropy state function is the amount of information in the system that is needed to fully specify the microstate of the system. Entropy is the measure of the amount of missing information before reception. [ 74 ]
