- All the processes shown below have the same inital pressure (2 atm
= 2 x 105Pa) and volume (100 cm3) and end at the same
values of pressure (2 atm) and volume (300 cm3). Which diagrams
represent the same amount of work done by the system?
- Starting from the point shown sketch
- For each case below describe whether the diagram represents a possible
(i.e. does not violate the Laws of Thermodynamics) heat engine or
refrigerator. If not describe what is wrong.
- On a warm day your roommate suggests that you leave the refrigerator
door open to "cool this place down." After a while with the fridge door open will
the room be cooler, the same or warmer? Explain.
