- bliuzodt to mopolb 9. If machine parts are degreased by means of kerosene as shown in the diagram, how much kerosene make-up is needed per day? How much kerosene has to enter the degreasing vat per day? There are about 3 lb of grease per 100 lb of machine parts, and 60 tons of machine parts are processed each day. Five thousand pounds of kerosene (the 10% solution) are carried away by the machine parts each day but drip off and are caught and put back in the degreasing vat. Two hundred pounds of the 10% solution are lost each day from the vat by evaporation, spillage, or by being carried away.1) A piston-cylinder system containing 1100 grams of an ideal gas ‘X’ is cooled from 900 K to 100 K at constant pressure. The specific heat capacity of the gas is Cp = 38.3 J.mol-1.K-1. Assume Cp stays constant in the given temperature range. The molar mass of the gas = 28 g.mol-1. a) Write the simplified first law of thermodynamics for this system with justification. b) Calculate the total heat transferred (in kJ) during the process of cooling c) If the entire heat from the cooling of ‘X’ (as calculated in (b)) could be used as work to change the volume of another gas ‘Y’ from 500 m3 to 1000 m3 in a constant pressure process, calculate the value of pressure. d) Instead of cooling at constant pressure, if ‘X’ was expanded reversibly and at a constant temperature (300K), calculate the work done by the system in kJ if the change in volume was 10-fold.Q1: If a calorimeter is not assumed to be adiabatic, how would one calculate the heat transfer? Guide Questions: What are the parameters to be considered and the equations to be used? What law of thermodynamics does this transfer of heat to the surroundings touch? Is an adiabatic system automatically considered as a closed system? Please help me understand by also attaching a reference/book/journal article. This would help me in my essay. Thank you.

- A Boeing 767 due to fly from Montreal to Edmontonrequired refueling. Because the fuel gauge on the aircraft was not working, a mechanic used a dipstick todetermine that 7682 L of fuel were left on the plane.The plane required 22,300 kg of fuel to make the trip. Inorder to determine the volume of fuel required, thepilot asked for the conversion factor needed to converta volume of fuel to a mass of fuel. The mechanic gavethe factor as 1.77. Assuming that this factor was in metric units the pilot calculated the volume to beadded as 4916 L. This volume of fuel was added andthe 767 subsequently ran out the fuel, but landed safelyby gliding into Gimli Airport near Winnipeg. The errorarose because the factor 1.77 was in units of pounds perliter. What volume of fuel should have been added?A silver cube with an edge length of 2.24 cm and a gold Substance Specific heat (J/g.°C) Density (g/cm³) cube with an edge length of 2.63 cm are both heated to gold 0.1256 19.3 84.8 °C and placed in 115.0 mL of water at 20.5 °C . silver 0.2386 10.5 What is the final temperature of the water when thermal water 4.184 1.00 equilibrium is reached?
