Problem

Ten moles of a diatomic perfect gas are allowed to expand at constant pressure. The initial volume and temperature are

V_0

and

T_0

, respectively. If

\frac{7}{2}RT_0

heat is transferred to the gas, then the final volume and temperature are a.

1.1 V_0, 1.1 T_0

0.9 V_0, 0.9 T_0

1.1 V_0, \frac{10}{11} T_0

0.9 V_0, \frac{10}{9} T_0
