Splet09. mar. 2024 · Using the equation of henry’s law, C = k P. C = 25 × 6. C = 150 mol/L. Therefore, the concentration of an argon gas dissolved in water is 150 mol/L. Problem 4: Calculate the partial pressure of a lithium gas dissolved in water. If the concentration of a lithium gas is 20 mol/L and the value of henry’s law constant, k = 5 L atm/mol. SpletTherefore, in one dimension, the equation can be represented as: Qcond= kA (T1 − T2 / Δx) = −kA (ΔT / Δx) If Δx 0, the equation in differential form can be written as: Qcond = −kA (ΔT / Δx) Thus, the 3-dimensional form of Fourier’s law is: q = - k\(\bigtriangledown\)T Fourier’s Law Also Read:Branches of Physics Important Forms of Fourier’s Law income tax first time malaysia https://buildingtips.net
