Thermodynamics

Statements of Heat Energy basis of Second Law of Thermodynamics Heat energy can easily be obtained from different energies including mechanical energy: but without heat…

Comparatively Explanation on the first and the second law of thermodynamics It is essential to know the difference between the two laws of thermodynamics. The…

Heat, Internal Energy, and Work: Relation We know, when a gas expands, it itself does some work on the surroundings. On the other hand when…

Measurement of the total internal energy of a body It is not possible at all to measure the total internal energy of a body. But…

Internal Energy of a System Put pressure by hand on a balloon filled with gas. You will see that the ballon is also giving pressure…

Conditions and Characteristics for adiabatic change The process in which a system neither receives heat nor rejects heat is called adiabatic process. The change in…

Adiabatic change When a gas is suddenly compressed then an amount of heat is produced. If this heat is not removed, then the temperature of…

Thermal system Suppose a piston, attached to a cylinder filled with gas is made to move by applying heat, hence the piston along with the…

Conditions and Characteristics of isothermal changes The change in which pressure and volume of a gas are changed but the temperature remains constant that change…

Isothermal change This is a change where the temperature of the gas remains constant and to achieve this we will have to either add or…
