This question is about work and pressure A frictionless piston cylinder contains a gas at a pressure of 200 kPa. The cross-sectional area of the piston is 0.04 m?. Heat transfers to the gas, and as a result, the piston and load are raised through a distance (x) of 0.4 m. Assume the atmospheric air pressure to be 100 kPa. (Hint: this process is isobaric) (i) Is this an open system or a closed system and why? (ii) Draw a sketch showing the process occurred from the initial to the final states, include a p-V diagram. (iii) Calculate the total work done by the gas. If the system is redefined to include the gas and the piston, determine (iv) The total work done by the system (gas and piston). (v) The total work done by the surrounding. (vi) In your own words, explain how work and heat are related in terms of energy in thermodynamic.
