Answer to Question #305393 in Molecular Physics | Thermodynamics for shoning

Question

Helium is contained in a 3 𝑚3 rigid volume at 60℃ and 100 kPa. Find the heat transfer needed to increase the pressure to 1000 kPa.

Answer 1

$\nu=\frac{p_1V_1}{RT_1}=108.4~mol,$

$T_2=\frac{p_2T_1}{p_1}=3330~K,$

$Q=\frac 32\nu R\Delta T=4~MJ.$
