Question
When an ideal diatomic gas is a heated at a constant pressure, the fraction of heat energy supplied which increases the internal energy of the gas is
Options
A.2/5
B.3/5
C.5/7
D.3/7
Solution
$\frac{\Delta U}{q_{p}} = \frac{C_{v,m}}{C_{p,m}} = \frac{\frac{5}{2}R}{\frac{7}{2}R} = \frac{5}{7}$
