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