A vertical piston-cylinder assembly contains 11.7 LL of air at 20^∘C. The cylinder has an internal diameter of 24 cm . The piston is 2.2 cm thick and is made of steel of density ρ=7830kg/m3ρ=7830kg/m3. Assume the atmospheric pressure outside is 101 kPa. 

a)- Determine the pressure of air inside the cylinder. The air is now heated until its volume doubles.

 b)- Determine the boundary work transfer during the process. 

c)- What would the pressure be if the piston weight were neglected? 

d)- What would the work be if the piston weight were neglected?
