QUESTION 8 A cylinder and piston assembly (the system) is warmed by an external flame. The contents of the cylinder expand, doing the work on the surroundings by pushing the piston outward against the external pressure. If the system absorbs 257 J of heat and does 608 J of work during the expansion, what is the value of the change in internal energy (AE) for this system. QUESTION 9 A cylinder and piston assembly (the system) is warmed by an external flame. The contents of the cylinder expand, doing the work on the surroundings by pushing the piston outward against the external pressure. If the system absorbs 373 J of heat and does 780 J of work during the expansion, what is the value of the change in internal energy ( AE) for the surroundings.
