Introduction :
A thermodynamic quantity in there the difference between the internal energy of a system and the multiplication of its absolute temperature and entropy.
I would like to give one example lift water from electric pump to up to 100 feet high and also store it then make it fall down like falls.By using this falls create electricity through the concept of mechanical energy has to convert in electricl energy.We can crate energy not that much what we spent alrady to produce electricty.
This is loss of enery.So we have to reseach such type of devices they have to concume less electricity / fuel.
Having problem with Derivative of Acceleration keep reading my upcoming posts, i will try to help you.
Energy
Energy can be defined as the capacity or ability to do work is mesured by the amount of work a bodycan do.So ,energy is measured in the same units as work,namely,joule. Like work.energy is a scalar quantity.
Energy can exit in various forms,such as heat energy,eletrical energy,sound energy ,light energy,chemical energy,nuclear energy,mechanical energy,etc. We will be mainely concerened with mechanical energy .Mechanical energy is of 2 types,kinetic and potential .
Law of Conservation of Energy
The law of conservation of energy states that the total energy of an isolated sysytem of particles remains constant ; the energy may change from one form to another.
Is this topic pressure equation hard for you? Watch out for my coming posts.
Free energy devices
In thermodynamics we know measure of the relative stability of a physical system chemical system. That exactly it does the system to react or change. If there change in free energy, then delta is negative.The change in free energy at a temperature depends on three factors, as seen from the equation Delta H - Delta TS = delta G
