How much ice (by mass) at a temperature of -19.9 degrees Celsius must be added to 325g of liquid water at a temperature of 60.1 degrees Celsius in order for the final temperature of both to reach 21 degrees Celsius. c of ice=2100 J/kg/C c of water=4190 J/kg/C Latent heat of fusion of water=3.34E5 J/kg/C a. .115kg b. 12kg c. 5 lbs d. .191kg

Provide complete solution and detailed diagram.  If the volume of 10 kg gas (cp = 0.92 KJ/kg-K) increases to three times the original volume, itsentropy change in KJ/kg-K is: A. 10.11      B. 8.34             C. 12.41           D. 32.34

Please help to solve complete solution.

In a cylinder of an automobile engine, immediately after combustion the gas is confined to a volume of 53.0 cm³ and has an initial pressure of 3.60 × 106 Pa. The piston moves outward to a final volume of 300 cm³, and the gas expands without energy transfer by heat. (Assume the gas in the engine is diatomic with y 1.40.) (a) What is the final pressure of the gas (in kPa)? = 317.920813906 kPa (b) How much work is done by the gas in expanding (in J)? 238.559389571 J (c) What If? If the engine operates in an ideal Otto cycle and 0.0125 mol of fuel-air mixture is injected into the cylinder during the intake stroke, what are the temperatures (in K) at points A, B, C, and D of the cycle as shown in the figure?
