A gas contracts from an initial volume of 3.83 L to a final volume of 2.33L against an external pressure of 810. mmHg. During the contraction the gas absorbs 10. J of heat. The gas is the system. Which of the following is true: 1. Heat flows into the system from the surroundings and the sign of a sys will be positive and the sign of w sys is positive. 2. The system is doing work on the surroundings. 3. Need more information such as an equivalence statement to answer this question. 4. Heat flows from the system into the surroundings and the sign of a sys will be positive and the sign of w sys is negative. 5. The change in the energy of the system AE is negative.
