Under what conditions will the quantity q be a positive number and the quantity w be a positive number? Oq is positive when the system loses heat to surroundings, w is positive when the surroundings does work on the 4 system. qis positive when the system loses heat to surroundings, w is positive when the system does work on the surroundings. qis positive when the system gains heat from surroundings, w is positive when the surroundings does work on the system. O qis positive when the system gains heat from surroundings, w is positive when the system does work on the surroundings.
