A vertical axis cylinder 0.075m² in cross sectional area is open to the atmosphere at one end and closed at the other by a piston which supports a mass of 85 kg. the piston is supported by compressed air. 5.46kJ of heat is transferred to the air and the piston lifts the mass through 55cm. What is the increase in internal energy, U, during the process? Draw the path of the process on a PV diagram.

P_atmos= 1.03 bar Ans=0.75 kJ

The figure below shows a closed cylinder with cross-sectional area A = 2.60 m2. The upper and lower circular surfaces of a vertically-oriented cylinder are labeled A. Electric field vector E points vertically upward, going up through the lower surface, up through the cylinder, and finally pointing up through the upper surface. The constant electric field E has magnitude 1.85 ✕ 103 N/C and is directed vertically upward, perpendicular to the cylinder's top and bottom surfaces so that no field...
