Question

thermodynomic first law mathematically ​

Answer 1

Answer:

First Law of Thermodynamics

Heat as energy was not physical law until it was demonstrated by James Prescott Joule. In tying a descending mass to a paddle wheel immersed in water, and measuring the increased temperature of the water as the mass dropped, Joule solidified the first law of thermodynamics: heat and work are forms of energy, and energy is conserved.

Mathematically, the first law can be written as

\Delta U=\Delta Q+\Delta W,

ΔU=ΔQ+ΔW,

where \Delta UΔU is the internal energy of the system, \Delta QΔQ is the heat supplied to the system, and \Delta WΔW is the work done to the system

Answer 2

∆U=Q-T

energy cannot be gain and cannot be loss but it change from one kind to another
