Rotational Mechanics : Moment of Inertia


Learning how to calculate Moment of Inertia is the first step to studying Rotational Mechanics. And calculating Moment of Inertia is a bit tricky, you may be considering the wrong dM or performing some logical or calculating error. This post is going to Involve some Basic Integration. That is the only prerequisite.

Enthalpy, Entropy and Free Energy


Entropy

Once you know how to calculate various Thermodynamic quantities involved in a reaction, the next thing you need to determine is whether the reaction is feasible or not. Will it occur as you imagine it or will nothing happen. How to determine it is what we will be covering in this post.

The basics that you need to know are :
  1. Knowledge of First Law of Thermodynamics 
  2. How to calculate ΔQ, ΔW and ΔU for various processes.
  3. Concept of Cp and Cv
