Table 3.3 shows the molar heat capacities of some dilute ideal gases at room temperature. is latex allergy genetic

"WebAlso, for 1 mol of an ideal gas, d ( p V) = d ( R n T), so p d V + V d p = R n d T and d T = p d V + V d p R n. We now have two equations for dT. Upon equating them, we find that C V n V d p + ( C V n + R n) p d V = 0. Now, we divide this equation by npV and use C p = C V + R. We are then left with C V d p p + C p d V V = 0, which becomes " - Four moles of a perfect gas heated
