The adiabatic Bulk modulus of a perfect gas at pressure is given by
$P$
$2P$
$P/2$
$\gamma P$
A monoatomic gas at pressure $P$ and volume $V$ is suddenly compressed to one eighth of its original volume. The final pressure at constant entropy will be $.....P$
What is cyclic process ? Write note on it.
When a gas expands adiabatically
Jet aircrafts fly at altitudes above $30000 \,ft$, where the air is very cold at $-40^{\circ} C$ and the pressure is $0.28 \,atm$. The cabin is maintained at $1 \,atm$ pressure by means of a compressor which exchanges air from outside adiabatically. In order to have a comfortable cabin temperature of $25^{\circ} C$, we will require in addition
In the following figure, four curves $A, B, C$ and $D$ are shown. The curves are
