Assuming constant pressure, rank these reactions from most energy released by the system to most energy absorbed by the system, based on the following descriptions: A Surroundings get colder and the system decreases in volume. B. Surroundings get hotter and the system expands in volume. C. Surroundings get hotter and the system decreases in volume D. Surroundings get hotter and the system does not change in volume. Also assume that the magnitude of the volume and tempera changes
