Question 447: Thermodynamics & KTG

Question

n moles of an ideal gas with constant volume
heat capcity CV 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

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