Which of the following is the equation for first law of thermodynamics when the process is adiabatic?

Write mathematical equation of first law of thermodynamics for the following processes :
Adiabatic process.

The mathematical expression for the first law of thermodynamics is,ΔU = q + wWhen ΔU = change in energy             q = heat absorbed by the system             w = Amount of work doneAdiabatic Process : A process in which heat is not allowed to enter or leave the system at any stage the process is called adiabatic process.∴ q = 0The mathematical expression for first law of thermodynamics is,ΔU = q + w

∴ ΔU = + w

Concept: Chemical Thermodynamics and Energetic - First Law of Thermodynamics
