Thermodynamics Formula is a subfield of physics that studies the interactions between internal energy, work, and heat transmission. In thermodynamics, the system is defined as a quantity of matter or a system in space under observation. The environment, often known as the surroundings, is everything outside of the system. The boundary line is the theoretical or physical line dividing the system from its surroundings.

Work done in different Thermodynamic processes Work done in isobaric (constant pressure) process, W = PΔV Work done in isochoric (constant volume) process, W = PΔV = P * 0 = 0 Work done in isothermal( constant temperature) process, W = -nRTln ( V 2/ V 1) = -2.303nRTlog( V 2/ V 1) Here, n = number of moles of gas R = Gas constant T = temperature of system Work done in adiabatic process,Also Check - Transmission of Heat Formula
