Please show all working so I can learn the material.
Partial answers I have are W1-2 =117KJ, Wspring/W12 = 0.641
Hopefully that helps you verify your answer a bit. Thank you in
advance!
SP7: (20 points) Hydrogen gas is contained in a vertical piston-cylinder device at 140 kPa and 0.3 mº. At this state, a linear spring with a spring constant of k=150,000 N/m touches the top of the piston but exerts no force on it because the spring is...
Help!!! Please explain why you chose the answers too pls: #1. What best describes what happens when the end of the hose of a running vacuum cleaner is placed on your arm? A. Your skin moves in the direction of negative pressure, partially into the end of the hose. B. The vacuum cleaner pulls your skin partially into the end of the hose. C. Your skin pushes itself partially into the end of the hose. D. The surrounding atmosphere pushes...
please show work and explain each part clearly
9. The curve given by its equation in polar coordinates: r = 1+ cose. The graph of the curve is shown on the graph below. a) (Spes) Find the slope of the tangent to the curve at the point where ark (draw) the tangent on the graph below. b) (7pts) Find the area of the region bounded by the curve in the first quadrant
An ideal monatomic gas is contained in a cylinder with a movable
piston so that the gas can do work on the outside world, and heat
can be added or removed as necessary. The figure shows various
paths that the gas might take in expanding from an initial state
whose pressure, volume, and temperature are , , and respectively. The gas expands to a state with
final volume . For some answers it will be convenient to
generalize your results...
It's a lot, but I really don't
understand these questions. Please explain! Thank you!
QUESTION 2 What volume (in L) is occupied by 1.29 moles of gas at -24.5 °C with a pressure of 704 mm Hg? QUESTION 3 A piston with a volume of 800.8 mL is filled with a gas at 304.1 K and 717.4 mm Hg. The piston is then compressed by 192.4 mL and cooled to 243 K. What is the pressure in atm) of the...
explain every answer choice well please and thank you.
The picture shows 6 moles of an ideal gas in a piston, undergoing a cyclic process A-B-C-D-A. P(atm) P1 13.What does the expression (V2-V)( P2-P1) show? (A) The internal energy at point B. (B) The heat flowing into the gas going from point A to point B (C) The work done by the gas going around the cycle (D) The temperature difference between point B and point A. (E) None of...
Please explain and show all work. Thank you!
Starting from the initial state shown, draw a pV diagram for the three step process: (a) An isochoric process that halves the temperature (b) An isothermal process that halves the (new) pressure (c) An isobaric process that doubles the (new) volume .V
The figures show the PV (pressure versus volume) graphs of two processes represented by straight lines The area under the curve equals the work. If volume Vinceases (V > V:) in a process, work W is positive. If volume V deceases (V <V) in a process, work W is negative. Case 1: In the left figure, pressure PA = 4.60 X 106 Pa. pressure P. = 14.72x 106 Pa. Volume VA = 0.0016 m, VA = 0.0048 m3. Don't use...
Answer the questions using the data and graph. please show all
work. Thank you
Titration of Hydrochloric Acid: 1) Use the buret that is located near the hydrochloric acid container to dispense 25.00 mL of hydrochloric acid solution into a clean dry 100 mL beaker. Record the molarity of this solution on your data sheet. 2) Check to make sure that the volume on your sodium hydroxide buret reads 0.00 mL. If it does not read 0.00 mL, adjust it...
Need help with Thermodynamics Homework. WILL RATE HIGH! Thank you! Please answer them all for high rate 1. Carbon Oxide (CO) initially occupying 2.9 m3 at 7.4 bar, 246.85°C undergoes an internally reversible expansion during which pV1.4 = constant to a final state where the temperature is 36.85°C. Assuming the ideal gas model, determine the entropy change, in Joules/K. 2. Water at 10 bar, 240°C enters a turbine operating at steady state and exits at 4 bar. Stray heat transfer...
