2. (6 points) Part1 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: (3 points) A. Surroundings get hotter and the system increases in volume. B. Surroundings get colder and the system expands in volume. G: Surrondings get-eolder-and the system expands involume: D. Surroundings get colder and the system does not change in volume. The q of the system is +/?+ The valuc of w is AE is +/-or undetermined system Solution since we know, U= q+ w, where U = total energy q = heat energy w = work therefore, for system we can write, A: q of system is positive and w of system is positive B: q of system is negative and w of system is negative C: q of system is negative and w of system is positive D: q of system is negative and w of system is zero so the ranking would be, B>D>C>A, also B>D>A>Ccan be true. without data we can not compete A and C. .
