QJEEM19Ph2f00: JEE Main 2019 Physics - Class 11 JEEM19Ph2f00 Solution: n moles of an ideal gas with constant volume heat capcity C V…

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 :

Multiple Choice Options

  • A nRCV−nR{{nR} \over {{C_V} - nR}}
  • B 4nRCV−nR{{4nR} \over {{C_V} - nR}}
  • C 4nRCV+nR{{4nR} \over {{C_V} + nR}}
  • D nRCV+nR{{nR} \over {{C_V} + nR}}

Step-by-Step Verified Solution

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