Question

The work done in compressing a gas isothermally is given by :

(a) \(\cfrac{γ}{γ-1}\) p₁V₁ \(\left[\left(\cfrac{p_2}{p_1}\right)^{\frac{γ-1}y}-1\right]\)

(b) mRT₁ log_e \(\cfrac{p_2}{p_1}\) N.m

(c) mc_p (T₂ – T₁) kJ

(d) mRT₁ \(\left(1-\cfrac{T_2}{T_1}\right)kJ\)

Answer 1

(b) mRT₁ log_e \(\cfrac{p_2}{p_1}\) N.m
