Question: A system at constant pressure undergoes the following three processes at 25 oC. I. 5 kJ of heat is released into the surroundings

A system at constant pressure undergoes the following three processes at 25 oC.

I. 5 kJ of heat is released into the surroundings

II. 10 kJ of work is done on the surroundings

III. 15 kJ of heat is absorbed by the system

Q4. Please draw a picture to depict the flow of energy into and out of the system as described in the question. Be sure to label the system and surroundings.

Q5. What is the total change in internal energy for the system after it undergoes all three processes? Show work to support your answer.

Q6. Is the overall enthalpy change exothermic, endothermic, or neither? How can you tell?
