Gas at a pressure of 0.85 bar, volume 0.25m^3 and temperature 18°c, is compressed until the pressure is 2.8 bar and volume is 0.115m^3, calculate the compression index and the final temperature.

n=1.53

T₂ = 166.16 °C

Explanation:

Given that

P₁=0.85 bar

V₁= 0.25 m³

P₂=2.8 bar

V₂=0.115  m³

Lets take compression index is n

So

Now by putting the values

ln 3.29 = n ln 2.17

n=1.53

T₁=18°C=273+ 18 = 291 K

Lets final temperature =T₂

T₂=439.16 K

T₂ = 166.16 °C

its c its is a mixture of gases
