BCH4024 F2024 OC E4 Q46: Rаs prоtein is cоnsidered а mоleculаr switch for cell growth and proliferation. Ras is activated for signaling cell growth by _______________.
Energy cаnnоt be creаted nоr destrоyed, but it cаn be transferred between a system and its surroundings. The change in internal energy, ΔU, is positive if the system absorbs energy, and it is negative if the system releases energy. Part A Define the total change in internal energy. Part B Classify the following by the sign of ΔU for the system (positive, negative or not enough data). (1) The system expands and the surroundings get hotter (2) The system contracts and the surroundings get colder (3) The system expands and the surroundings get colder (4) The system contracts and the surroundings get hotter Part C A gaseous reaction occurs at a constant pressure of 45.0 atm and releases 65.1 kJ of heat. Before the reaction, the volume of the system was 7.80 L . After the reaction, the volume of the system was 2.60 L . Calculate the total internal energy change, ΔU, in kilojoules. Part D Interpret the result from C. Part E A gas is confined to a container with a massless piston at the top. A massless wire is attached to the piston. When an external pressure of 2.00 atm is applied to the wire, the gas compresses from 5.90 to 2.95 L . When the external pressure is increased to 2.50 atm, the gas further compresses from 2.95 to 2.36 L . In a separate experiment with the same initial conditions, a pressure of 2.50 atm was applied to the gas, decreasing its volume from 5.90 to 2.36 L in one step. If the final temperature was the same for both processes, what is the difference between q for the two-step process and q for the one-step process in joules? Express your answer with the appropriate units. Solve this problem on paper, document your approach and provide intermediate results. Report the final answers with 3 significant figures.
