Helium gas has cv = 12:5 J mol^-1K^-1. n = 100 mol of helium gas ini- tially has volume 0.2 m3 and pressure 5 106 Pa. Find the energy transfer by heating if pressure increases by 50% due to an isochoric process. (You do not need to know n but I include it in case you use a dierent method).
(d) Helium gas has c 2.5 mol-K-. n 100 mol of helium gas ini- tially has volume 0.2 m3 and pressure 5 x 106 Pa. Find the energy transfer by heating if pressure increases by 50% due to an isochoric process. (You do not need to know n but I include it in case you use a different method)
A tank of volume 0.438 m3 contains 1.35 mol of helium gas at 52 ◦C. Assume that the helium behaves like as an ideal gas. The universal gas constant is 8.31451 J/K mol, and Boltzmann’s constant is 1.38066 × 10−23 J/K. What is the average kinetic energy per molecule? Answer in units of J
