Theorem of corresponding states
According to van der Waals, the theorem of corresponding states (or principle/law of corresponding states) indicates that all fluids, when compared at the same reduced temperature and reduced pressure, have approximately the same compressibility factor and all deviate from…
Heat capacity specific heat
As shown originally by Count Rumford, there is an equivalence between heat (measured in calories) and mechanical work (measured in joules) with a definite conversion factor between the two. The conversion factor, known as the…
What is an ideal gas?
Gases are complicated. They're full of billions and billions of energetic gas molecules that can collide and possibly interact with each other. Since it's hard to exactly describe a real…
Reversible And Irreversible Processes
We see so many changes happening around us every day such as boiling of water, rusting of iron, melting ice, burning of paper, etc. In all these processes we observe…
Zeroth Law Of Thermodynamics
Zeroth law of thermodynamics is one of the four laws of thermodynamics. The credit for formulating the law goes to Ralph H. Fowler. Interestingly, the zeroth law of thermodynamics was actually…
Internal Energy
One of the thermodynamic properties of a system is its internal energy, E, which is the sum of the kinetic and potential energies of the particles that form the system. The internal…
What are Laws of Thermodynamics?
The laws of thermodynamics define the fundamental physical quantities like energy, temperature and entropy that characterise thermodynamic systems at thermal equilibrium. The laws represent how these quantities behave under various…
What is Thermodynamics?
Thermodynamics is the branch of Physics which is concerned with the relationship between other forms of energy and heat. We can define thermodynamics as: To be specific, it explains how thermal…
Oxygen Candles:Providing Emergency Air
Oxygen candles are used as a backup source of breathable air in an emergency. They supply an on-demand source of oxygen, utilised in aeroplanes, space stations as well as other applications such…
