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...
Classifying the systematic mistakes made by students in response to a concept-based question on work done in thermodynamics, and sharing them across a public forum results in a paradigm of learning called the 'mistake based approach'. This approach is a subset of a popular genre in science ...
A gas follows the PV diagram as shown in the figure. Find the work done on the gas along the paths (a) AB, (b) BC, (c) CD, (d) DA, and (e) ABCDA. Work- done in thermodynamics from P-V diagram:Work-done on gas i...
To determine when the work done by a gas during expansion is greatest, we need to analyze the different thermodynamic processes: isobaric, isothermal, and adiabatic.1. Understanding Work Done in Thermodynamics: The work done
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...
In thermodynamics, the amount of work done depends on the external pressure and change in the volume of a system. When a system does work, then it is considered to be negative. In contrast, work done on a system is considered p...
Total work done from the initial to the final state is equal to the summation of the three works done above: Wtotal = W12 + W23(const) + W23 (spring) Wtotal = 33.333 + 33.333 + 27.562 = 94.228 Joules of work done. Is my approach to this question reasonable? If not what can I...
The first law of thermodynamics—conservation of energy—says the earth must end up with the same amount ofenergy it started out with. The energy changes forms, but no energy is lost orgained.1.How does the field of physics define “work”?A) It is the research done by physicists in a...
Torque - Work done and Power Transmitted The work done and power transmitted by a constant torque. Work done Work done is the force multiplied with the distance moved by the force - and can be expressed as W = F s (1) where W = work done (J, Nm) F = force (N) s = ...
The term 'work' has been used in this model in the sense of economic activity to include not only work done by people but also by machines. The model shows 8 positive feedback loops that reinforce work and the need to work. From the perspective of physics, civilisation can be described ...
