So my q is according to 1St law of thermodynamics when work is done on the system the volume will decrease .... according to theory of expansion when heat is added the volume will increase ... so how can u relate this two ?? Tnx

what, who says the volume of the system will decrease when a work is applied to it that is wrong, the whole point of the first law of thermodynamics is that energy can neither be created nor destroyed, only altered in form. For any system, energy transfer is associated with mass crossing the control boundary, external work, or heat transfer across the boundary. These produce a change of stored energy within the control volume. or in another word, the entropy (order of chaos) of a system will always increase.
Oct 24, 2021May be .... work done on the system malet systemu energy apply tederigobet endegena yehonech yahil distance heduwal met nw Gin like metal lin heat energy siyagegn net yehone distancu 0 nw emihonew malet beye direction nu expand yaregal be left 3 cm kerezeme be right 3 cm yirezim so net yehone direction yeteguwazew 0 nw siketil betam tinish distance nw emisefaw ke orginalun So when we multiply the energy by the distance malet be 0 we get 0 work done on the system 😂😂😂😂😂 betam bizu sihitet endemitagegnibet tesifa aregalew 😇

Oct 30, 2021Volume is equal to Mass over density ,we know that when heat or temperature is applied to some body(object) it will increase it's surface area (Size) because of expanding of the molecules that make it. And also in high heat and temperature the molecules of aparticles are move faster than a molecule with lower heat and temerature(Heavier molecules move faster and lighter molecules move smaller in fluid submerging and also in air. The law states conservation of Energy .
