In thermodynamics, the P−V work done is given by w=−∫dVPext. For a system undergoing a particular process, the work done is , w=−∫dV(RTV−b−aV2) The equation is applicable to a Asystem that satisfies the van der Waals equation of state. Bprocess that is reversible...
In mechanics, all notions of “work” have something to do with force times distance. The conventional definition of work doneonan object is: work =∫ Γ F· ds(6) where the integral runs along some path Γ, namely the path taken bythe point of applicationof the force, and where the ...

In thermodynamics, adiabatic processes are those where no heat exchange takes place between the work substance and the environment. Adiabatic processes can be classified in: ∙ Reversible, satisfying the polytropic equation, pVγ=C, where γ=cp/cv is the ratio between the specific heats at ...

Can I say that it is equal to the work done in an isothermal proccess (##dQ=Pdv##)? My reasoning : We have ##dQ=C_V d\theta + Pdv##. For constant temperature it becomes :$$dQ=Pdv$$ MatinSAR Thread Jan 30, 2024 Heat Thermodynamics Work Replies: 2 Forum: Introductory Physics...
How much work must be done on a system to decrease its volume from {eq}14.0 \ L {/eq} to {eq}5.0 \ L {/eq} by exerting a constant pressure of {eq}4.0 \ atm {/eq}? Work in thermodynamics The first law of thermodynamics ...
Work done on a body is equal to the increase in the energy of the body, for work transfers energy to the body. If, however, the applied force is opposite to themotionof the object, the work is considered to be negative, implying that energy is taken from the object. The units in wh...
In physics, the term work refers to the transference of energy that occurs when a force is applied to a body that is moving in such a way that the force has a component in the direction of the body's motion. Thus work is done on a weight that is being lifted, or on a spring tha...
