A sample of a monatomic ideal gas contains N atoms. You want to compress the gas slowly to 1/4 of its original volume. A. By what factor must you change the absolute temperature of the sample in order in order to increase its entropy by 4N. Express the answer to 3 sig figs. Tf/Ti= B. For this process, by what factor does the root-mean-square speed I'd the gas particles change? Express the answer to 3 sig figs. Vrmsf/Vrmsi=

A vessel contains 5900 oxygen molecules at 520 K having Maxwell-Boltzman distrubution function. The universal gas constant is 8.31451 J/K mol. Determine the most probable speed if the molecular mass of oxygen is 0.032 kg/ mol. Answer is m/s. Find the average speed for the molecules of the gas in m/s. Find the root-mean-square speed for the particles in the gas in m/s. I added more points since this is multiple questions. Thanks!
