$A$ cycle tyre bursts suddenly. What is the type of this process?

$A$ polyatomic gas $\left(\gamma = \frac{4}{3}\right)$ is compressed to $\left(\frac{1}{8}\right)^{\text{th}}$ of its volume adiabatically. If its initial pressure is $p$,its new pressure will be (in $p$)

The temperature of the system decreases in the process of

$A$ given system undergoes a change in which the work done by the system equals the decrease in its internal energy. The system must have undergone an

$A$ tyre filled with air ($27^\circ C$ and $2 \text{ atm}$) bursts. What is the final temperature of the air in $^\circ C$? (Given: $\gamma = 1.5$)

In an adiabatic expansion,the product of pressure and volume:
