Web27 mrt. 2024 · To find this result: Convert the temperature into kelvin: T [K] = 273.15 + 50 = 323.15 K. Compute the product of temperature, the number of moles, and the gas constant: nRT = 0.1 mol × 323.15 K × 8.3145 J·K/mol = 268.7 J (that is, energy ). Divide by the volume. In this case, the volume is 1, hence: P = 268.7 Pa. WebSolution The correct option is A q= −w=5.22 kJ and ΔU = 0 In an isothermal process, temperature remains constant so ΔU is zero According to the first law of thermodynamics, ΔU = w+q 0 =w+q q = −w For a reversible isothermal process, w= −2.303 nRT log10 P 1 P 2 = −2.303×1×8.314×273log10 1 0.1 = −5227.1 J = −5.22 kJ Thus, q = −w=5.227 kJ and … Web2 days ago. 23.29 inches of mercury (Hg) is equivalent to 0.787 atmospheres (atm). Atm and Hg relate to each other: 1 atm = 29.92126 inches of Hg. If you want to convert mercury (Hg) to atmospheres (atm) you will have to divide the number of inches of mercury by 29.92126. In your example, 23.29 inches of Hg / 29.92126 ≈ 0.787 atm. lowe\\u0027s pergo duracraft
