I rearranged to ρ = P / RT but would the density not differ when the air is in the cylinder?
Or is the temperature of the air inside of the cylinder the same as the temperature in the tank?
Thank you again for your help, although I cannot think of a way to calculate the density of the air without knowing the mass of it inside of the cylinder.
Again sorry if I am missing something very obvious here.
I see thank you for your help.
I calculated the area of the piston to be 0.018m2 which gave me a new value of Absolute pressure as 139.48kPa.
Would I be correct in using the density of the air in the cylinder as 1.225kg/m3 as looking back I do not think this is correct.
I think I have to...
