Five moles of an ideal gas expands isothermally at 100$\degree$C to five times its initial volume. Find the heat flow into the system.

Question

Quizplus · Accepted Answer

The heat flow into the system during an isothermal expansion of an ideal gas can be calculated using the formula Q = nRT ln(Vf/Vi). Here, n = 5 moles, R = 8.314 J/mol·K, T = 373 K, and Vf/Vi = 5. Substituting these values gives Q = 5 * 8.314 * 373 * ln(5) ≈ 2.5 * 10^4 J.
