Hello, can someone please help me solve this? How much kinetic energy would an electron depart a magnesium plate, with work function of ø= 5.86x10^ -11J, if light with a wavelength of 100 nm was shined on it?
To whom it may concern, Hello, I need help with this question: Question: "A cylinder with a piston contains 0.6 kg of water at 100 degrees C. What is the change in internal energy of the water when it is converted to steam at 100 degrees C at a constant pressure of 1 atm? The density of water is 1000 kg/m^3 and that of steam is 0.6 kg/m^3. The latent heat of vaporization of water is 2.26E+06 J/kg." Let me...
Can someone help me with calculating the change in temperature of a stream through a heat exchanger? I have the following info: The Cold stream is Tin = 90,, Tout =100, the heat exchanger is 30 kW, and the hot stream is saturated steam, with deltaHvap = 1676 kj/kg and T in = 258 C U of the heat exchanger is 1 kW/m^2*C but I don't think that's useful here? Thank you so much! Alice Shen

can someone help me with this question? You received no credit for this question in the previous attempt. A frictionless piston-cylinder device contains 12 lbm of superheated water vapor at 40 psia and 600°F. Steam is now cooled at constant pressure until 70 percent of it, by mass, condenses. Determine the work done during this process. Use steam tables. The work done during this process is 9808.34. Btu.
