1.	The pressure (10^(5) Nm ^(-2))of air filled in a vessel is decreased adiabatically so as to increase its volume three times. Calculate the pressure of air. Given gamma-for air = 1.4
Answer» <P> Solution :`P _(2) =P_(1) (V _(1) //V_(2))^( GAMMA) = 10 ^(5) (1//3) ^(1.4) = 2. 148 XX 10 ^(4) Nm ^(-2)`
