Energy Free energy Gibbs free energy Helmholtz Helmholtz free energy

AI Thread Summary

Enthalpy, Gibbs free energy, and Helmholtz free energy are essential thermodynamic concepts used to understand energy changes in chemical reactions and physical processes. Enthalpy measures the total heat content, while Gibbs free energy indicates the maximum reversible work obtainable from a system at constant temperature and pressure. Helmholtz free energy is useful for systems at constant volume and temperature, focusing on usable energy. Usable energy refers to the energy available to do work in a system, which is critical for predicting reaction spontaneity and equilibrium. A deeper understanding of these concepts aids in analyzing thermodynamic processes effectively.

Hello abi. I looked at a few earlier threads from you to place this question in a context. Did not succeed, so I have to ask you: Could you tell us a bit more so we may hopefully provide you with better assistance ?

Thread 'Condensate rate of water for an air conditioning cooling coil'

I need to calculate the amount of water condensed from a DX cooling coil per hour given the size of the expansion coil (the total condensing surface area), the incoming air temperature, the amount of air flow from the fan, the BTU capacity of the compressor and the incoming air humidity. There are lots of condenser calculators around but they all need the air flow and incoming and outgoing humidity and then give a total volume of condensed water but I need more than that. The size of the...

Thread 'Why work is PdV and not (P+dP)dV in an isothermal process?'

Let's say we have a cylinder of volume V1 with a frictionless movable piston and some gas trapped inside with pressure P1 and temperature T1. On top of the piston lay some small pebbles that add weight and essentially create the pressure P1. Also the system is inside a reservoir of water that keeps its temperature constant at T1. The system is in equilibrium at V1, P1, T1. Now let's say i put another very small pebble on top of the piston (0,00001kg) and after some seconds the system...

Thread 'What does equiprobable mean in the context of thermal motion?'

Hello! I read that the probability of a molecule moving with a certain velocity component in the x-direction is equal to the probability of it moving with the same velocity component in the y or z direction. I can't fully understand what does this mean and why are the square of the components of velocity equal? Could anyone explain it? Thanks.
