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...

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 ...
The first law of thermodynamics is a version of the law of conservation of energy. It states that for a closed system and for any process that begins and ends with equilibrium states, a change in U, the thermodynamic energy or internal energy of a system, is defined by the sum of the ...
since such work is defined bythermodynamic processwork ΔW = PΔV where P is pressure (no minus sign; this is work done by the system). By applying the first law of thermodynamics, we can deduce that ΔU the change in the system's internal energy, isfirst law of thermodynamics ΔU ...
I have been helping students in Physics, Chemistry, Biology, and Thermodynamics for 5 years. I have completed my all studies in Physics and chemistry at a well-reputed university and am now able to do any task related to Physics and Chemistry.You can surely rely on my wo...
Fermi level: the work done by the electron against the electric double layer force (ε0). 2. Work function: the work done by the electron against the electric image force (χ0). Fig. 2.4 shows the potential barrier at the metal-vacuum junction [1]. The potential barrier (W0) means th...
What is a joule in physical chemistry? What are the first and second laws of thermodynamics? Can the law of conservation of energy be broken? An electron has an energy of 2.3 eV. What is the kinetic energy of this electron in joules? What does the kinetic theory of matter state? What ...
If the system does 117J of work, then -117J of work is done on the system. Like a free body diagram in physics, are we supposed to focus on the work done to the system to determine the correct sign, or are we supposed to focus on the work the system does on the environment?
Confusion about work done by a gas - Thermodynamics This is chemistry but it's basically physics :D. I used PV = nRT, I get V = 37.44 L. This is fine. So then I have W = P(Vfinal - Vinitial). Vinitial is zero, because there was no hydrogen gas initially. So I get 3.78 ...
