Homework Statement
In the open cylindrical chamber is the piston of the total mass m. The initial air pressure inside the container is pa, the initial temperature T0. The initial height of the piston above the bottom h0. Now we start the gas supply heat to the moment when the piston reaches the height h above the bottom of the container .Air is ideal diatomic gas.
a / determine the final temperature T of the air inside the container
b / specify the total heat Q which air is received in the container
c / determine the efficiency of the piston stroke - ratio performed mechanical work and the total heat to the air inside the cylinder accepted
Homework Equations
F = mgΔh
W = F * ( h-h0) = p * S * ( h-h0) = p * ΔV
pV = nRT
paV0/T0 = p V/T
The Attempt at a Solution
[/B]
work necessary for the piston stroke of the mass m ...W = F*Δh = m*g*Δh = m*g* ( h-h0)
