Question

A sample of gas with =1.5 is taken through an adiabatic process in which the volume is compressed from 1200cm^3 to 300cm^3. If the initial pressure is 200kPa. The absolute value of the workdone by the gas in the process =J.

Accepted Answer

Correct answer: 480. (480) =1.5 p_1 _1^ =p_2 _2^ (200 ) (1200 )^1.5=P^2 (300 )^1.5 P_2=200 (4 )^3/2=1600 kPa (W .D . )= p_2v_2-p_1v_1v-1= ( 480-2400.5 )=480J

$A sample of gas with γ = 1.5 is taken through an adiabatic process in which the volume is compressed from 1200 c m^{3} to 300 c m^{3} . If the initial pressure is 200kPa. The absolute value of the workdone by the gas in the process =J.$
