# In a thermodynamic process, neon obeys the law $TP^{\large\frac{2}{5}}$ = constant. If the temperature of 2 moles of gas is raised from T to 5T, then the heat given to gas (consider ideal behaviour) is what?

$\begin{array}{1 1} 12\;RT \\ 9\;RT \\ zero \\ 16\;RT \end{array}$

Since for a neon gas $\gamma = \large \frac{5}{3}$ and for an adiabatic process $TP^{\large\frac{2}{5}}$ = constant $\rightarrow \Delta Q = 0$.
