WebMar 6, 2024 · First of all, the Charles' law formula requires the absolute values of temperatures so we have to convert them into Kelvin: T₁ = 35 °C = 308.15 K, T₂ = 15 °C = 288.15 K. Then we can apply the Charles' law equation in the form where the final volume is being evaluated: V₂ = V₁ / T₁ × T₂ = 2 l / 308.15 K × 288.15 K = 1.8702 l. WebSolving Problems Involving the Second Law of Thermodynamics Entropy is related not only to the unavailability of energy to do work; it is also a measure of disorder. For example, in …

WebTo find the final temperature Tf, we can use adiabatic equation of state. (ii) In an isobaric process the work done by the system W = P ∆V = P(Vf – Vi) and Vf = 2Vi so W = 2PVi To find Vi, we can use the ideal gas law for initial state. PiVi = RTi The work done during isobaric process, W = 2 × 106 × 24.9 × 10−4 = 4.9 kJ WebFew steps can help you to solve your problems and also improve your concepts. 1.
