- A 11.8 L gas tank containing 3.90 moles of ideal He gas at 26.0°C is placed inside a completely evacuated insulated bell jar of volume 39.0 L .A small hole in the tank allows the He to leak out into the jar until the gas reaches a final equilibrium state with no more leakage. Part A What is the change in entropy of this system due to the leaking of the gas? ■ ΜΕ ΑΣΦ AS = ? J/K Submit Request Answer Part B Is the process reversible or irreversible?arrow_forwardA-E pleasearrow_forwardThree moles of an ideal gas undergo a reversible isothermal compression at 20.0° C. During this compression, 1900 J of work is done on the gas. For related problem-solving tips and strategies, you may want to view a Video Tutor Solution of Entropy change in a free expansion.

- 5.97 Block A, with weight 3w, slides down an inclined plane S of slope angle 36.9° at a constant speed while plank B, with weight w, rests on top of A. The plank is attached by a cord to the wall (Fig. P5.97). (a) Draw a diagram of all the forces acting on block A. (b) If the coefficient of kinetic friction is the same between A and B and between S and A, determine its value.

- No chatgpt pls will upvote Alreadyarrow_forwardWhat fuel economy should be expected from a gasoline powered car that encounters a total of 443N of resistive forces while driving down the road? (Those forces are from air drag, rolling resistance and bearing losses.) Assume a 30% thermodynamic efficiency.arrow_forwardNo chatgpt pls will upvotearrow_forward
- 12. What is the angle between two unit vectors if their dot product is 0.5?arrow_forwardIf the car in the previous problem increases its power output by 10% (by pressing the gas pedal farther down), at what rate will the car accelerate? Hint: Consider the net force. In the previous problem the power was 31.8kWarrow_forwardWhat power is required (at the wheels) for a 1400 kg automobile to climb a 4% grade at a constant speed 30 m/s while it is opposed by drag and rolling resistance forces totaling 500 N?arrow_forward
