Answer to Question #67520 in Mechanics | Relativity for Mai

Question

4/ A 0.9 mol sample of an ideal gas undergoes an isothermal process. The initial volume is 0.20 m3 and the final volume is 0.40 m3. If the heat added to the gas is 2000 J, find the temperature of the gas.

5/ In an intestellar gas cloud (e.g., a star-forming region) at 20.0 K, the pressure is 1.010-8 Pa. Assuming that the molecular diameters of the gases in the cloud are all 15.0 nm, what is their mean free path?
