WebSolution. (a) We know that work done by the gas in an isothermal expansion. Since µ = 0.5. W = 1.369 kJ. Note that W is positive since the work is done by the gas. (b) From the … WebAmontons's law, Charles's law, and Boyle's law form the combined gas law. These three gas laws in combination with Avogadro's law can be generalized by the ideal gas law. Expansion of gases. absolute zero was approximately 266.66°C below 0°C. The value of the rate of expansion α is approximately the same for all gases and this is also ... takaya rice cooker

WebThe latest data confirm a Hubble constant or expansion rate of 73.0 ± 1.0 km/s/Mpc, bringing it no closer to meeting the alternative measure of 67.4 ± 0.5 km/s/Mpc. That gap (the 'Hubble tension') of 5.6 km/s/Mpc remains a significant problem – something is wrong somewhere, and now we're even more certain of it than ever. WebJun 5, 2014 · 3. CAF123 said: In this case, the system and the surroundings are not in equilibrium and work done by the gas in expanding is W = ∫P ext dV which is not the … WebJan 27, 2024 · That's the case for a free expansion into a vacuum.
