Question 388: Thermodynamics & KTG

Question

n moles of an ideal gas with constant volume
heat capcity C
V
undergo an isobaric expansion
by certain volume. The ratio of the work done
in the process, to the heat supplied is :

Accepted Answer

w = nR$$\Delta $$T
$$\Delta $$H = (Cv + nR)$$\Delta $$T
$${\omega  \over {\Delta H}} = {{nR} \over {{C_v} + nR}}$$

Answer

$${{nR} \over {{C_V} - nR}}$$

Answer

$${{4nR} \over {{C_V} - nR}}$$

Answer

$${{4nR} \over {{C_V} + nR}}$$

Answer

$${{nR} \over {{C_V} + nR}}$$
