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

A cylinder contains 0.0100 mol of helium at 27.0 ?C. How much heat is needed to raise the temperature to 67.0 ?C while keeping the volume constant?(4.99) If instead the pressure of the helium is kept constant, how much heat is needed to raise the temperature from 27.0 ?C to 67.0 ?C?(8.31 J) If the gas is ideal, what is the change in its internal energy in part A? If the gas is ideal, what is the change in its...
