The company has recently expanded their product range to include some aluminium components. Toaid in the manufacturing process michael has been asked by the production manager to determine theamount of heat energy required to exactly melt 40kg of aluminium at 20° C. The melting point ofaluminium is 660 °C, its latent heat of fusion is 387 kJ/kg and its specific heat capacity is 950J/kg.K.Briefly discuss the changes that occur within the copper during this process. please solve exact and accurate with complete steps and explanation..Thank you!!!!!
1. You have ice at 263 K (-10.0 °C) and 1.0 atm. Whatvcould you do to make the ice sublime? 2. A sample of dry ice (solid CO2) is cooled to 173 K (-100.0 °C), and is set on a table at room temperature (298 K; 25 °C). At what temperature is the rate of sublimation and deposition the same (assume that pressure is held constant at 1 atm)?
Carbon nitrating is a case hardening process in which a steel is heated in a gaseous atmosphere of such composition that carbon and nitrogen are absorbed simultaneously. Carbon nitridinf is a modification of the nitriding process.
10.7 One of the Hume-Rothery rules for solid solutions11 is that the solubilityof solute B in solvent A becomes negligible when the atomic radii of A andB differ by more than 15%. Plot the maximum solubility (atomic percent) of Ni, Pt, Au, Al, Ag, and Pb as a function of the ratio of solute and solvent (Cu) radii, and verify that the solid solubility in Cu drops precipitously at a size ratio of about 1.15. Use the following data:rNi = 0.1246 nm rAl = 0.143 nmrAg = 0.1444 nmrPt = 0.139 nm rPb = 0.1750 nmrCu = 0.1278 nm rAu = 0.1441 nm
