13. One kg of pure liquid water at 0°C is placed into an insulated tank containing 5 kg of seawater of salinity 3 percent and initial temperature 17.5°C. The system is al- lowed to reach equilibrium. Calculate the final temperature of the system. Express your answer in °C.

[Thermodynamics] kindly Answer it Correctly with explanation, If you are not sure skip it. 1) Evaluate whether the following statement is True or False: For an ideal gas, the change in enthalpy is equal to Cp (specific heat at constant pressure) times the change in temperature. “This relationship can be used for both constant volume and constant pressure processes.” -True -False -It depends, only true or false under certain circumstances

Need help on this Q

Give two reasons why it is important to pay attention thermal expansion and contraction in real life situations.

I need help on parts a and b, please. Part a is incorrect and I have no clue how to solve it correctly, please help. Thank you!

(Thermodynamics) Plz solve the question and show the steps

The properties of some very ductile metals, such as certain low- carbon steels, change at low temperatures at their particular transition zone. How can this information help an engineer design machinery that will be operating in subzero temperatures?

This question is for mechanical engineering. Please help me with this and explain. Thank you.

b) A 1.25 m long cable has a diameter 3.50 mm with a Young's Modulus, E, of 9.75 x 10⁹ N/m². When the wire is placed under tension, it experiences a stress of 202.52 x 106 N/m², the length of the cable extends by 36.35 mm. Calculate the force that the cable experiences under tension and the strain energy density (U/V) due to deformation. Give your answers in newtons (N) to 2 decimal places for the force; and in joules per cubic metre (J/m³) for the strain energy density to 2 decimal places. Assume the cable is solid and the material is homogeneous. c) Figure Q1c shows a bracket on rollers that allow the bracket to move along a beam in the horizontal direction. A force F₁ of 2625 N acts at point A where the angle between F, and the x-axis is 100. If force F₂ acts at an angle a = 400 between F2 and the y-axis: (i) Determine the magnitude of F2 necessary to maintain bracket on horizontal equilibrium. (ii) Determine the vertical force at A acting along the y-axis. Give your answers to the…

Question 1 You are working on a design team at a small orthopaedic firm. You have been asked to select a cobalt- chrome-molybdenum (CoCr) material that will not experience plastic deformation under a specific mechanical test, as follows... A tensile stress is applied along the long axis of a solid cylindrical rod that has a diameter of 10 mm. An applied load of some magnitude F produces a 7x10³ mm change in diameter (see figure below, original shape is blue, elongated shape is unshaded). Q1H: Provide a brief rationale based on calculations used to support your answer. That is, how would you explain the behavior of the "new alloy" material to your design team?
