ideal gases

Question 1

If dV = 0 is work done

Answer 1

no, as for work to be done there needs to be movement

Question 2

equations for a polytropic process

Answer 2

pV^n = constant

(p2/p1)^(n-1)/n = T2/T1

(V1/V2)^n-1 = T2/T1

Question 3

How do you calculate work done in a polytropic process

Answer 3

W = (P1V1-P2V2) / n-1
or
W = mR (T1 - T2) / n-1

Question 4

calculate work done when pressure is constant

Answer 4

P1(V2-V1)

Question 5

Equation for the ratio of specific heats γ and R

Answer 5

γ = Cp / Cv
R = Cp - Cv
