a quantity of perfect gas at 10 degree Celsius is adiabatically compressed to one third of its initial volume calculate the final temperature use Gamma equal to 1.5
Dear student,
T1 = 10 = 283K
Let initial volume be V1 and final be V2 .
Now, as gas is adiabatically compressed to one third of it's original volume then :
V2 = 1/3 of V1
That is :-
V2 / V1 = 1/3
And, gamma = 1.5
And since the gas is compressed, so we will use
T2 (V2)^(gamma - 1) = T1 (V1)^(gamma - 1)
Therefore it becomes -
T2 = T1 (V1/V2)^(gamma - 1)
T2 = 283 (3)^0.5 = 283√3
Therefore the final temperature is :-
T2 = 490.17K
