Need some help with physics...? - diagram of a 420 sailboat

When a gas following Route 123 in the diagram in Figure P12.50 PV, 420 J of energy in the system by heat and 170 J of work is on the gas sector.



(a) What is the change in internal energy of the system?
J
(b) Q As the energy flows into the system, whether the gas is 143 degrees? The work on the gas is done in this way -63.0 J
J
(c) How much work would actually net or through the system whether the system should be followed the path of 12,341?
J
(d) How much work would actually net or through the system whether the system should be followed the path of 14,321?
J
(e) What is the change in internal energy of the system in which to in paragraphs (c) and (d)?
J
