A diatomic gas with rigid molecules does $10 J$ of work when expanded at constant pressure. What would be the heat energy absorbed by the gas, in this process?

Options:

Answer:

Solution:

$C_{p} = \frac{7}{2} R$ (for diatomic gas)
$Δ Q = n C_{p} Δ T$ $(∴ I s o b a r i c p r o c e s s)$
$Δ W = n R Δ T = 10 J$
Given
$∴ Δ Q = n \times \frac{7}{2} R Δ T = \frac{7}{2} \times 10 = 35 J$ $\{n R Δ T = 10 J\}$
