Question

# A gas $$(\gamma = 1.3)$$ is enclosed in an insulated vessel fitted with insulating piston at a pressure of $$10^{5} N/ m^{2}$$. On suddenly pressing the piston the volume is reduced to half the initial volume. Thee final pressure of the gas is

A
20.7×105
B
21.3×105
C
21.4×105
D
None of these

Solution

## The correct option is B $$2^{1.3} \times 10^{5}$$Given: $$\gamma=1.3, P_1=10^5 N/m^2, V_1=2V_2$$As it is a adiabatic process, so using the relation$$\therefore PV^{\gamma }=k \left ( constant \right )$$$$P_1V_1^{\gamma}=P_2V_2^{\gamma}$$$$P_2=2^{1.3}\times 10^5 N/m^2$$Physics
