We are solidifying aluminum and iron melts in plaster molds. The melts are poured with no superheat and resistance to heat flow at the mold/metal interface and within the solidified metal are negligible. Plot thickness of the solidified layer, s, vs. (t)1/2. Repeat calculations also for a sand mold. What can you conclude?
why are the colors of iron, iron 2 sulfate and iron3 oxide different?
why are the colors of iron, iron 2 sulfate and iron3 oxide different?
Explain how a passive surface can be formed on iron.
1. Explain why identical twins actually still look different (distinguishable from each other) 2. Explain the mechanisms involved in mediating epigenetic events. What is the evidence that epigenetic events are essential to development, differentiation and aging? Please answer both questions. Thank you

Explain why Catasetum orchids have male and female flowers on the same plant that look very different. What specific type of selection best explains this outcome?
Question: Explain why solids do not minimize their surface area. (Please post a thoughtful and thorough explanation.) Hints: Reflect on the explanation of why liquids do minimize their surface area. How are solids different from liquids?
1) A block of iron at Tiiron- 500°C is placed on top of a block of ice (solid water) at Ti water-50°C in an insulating container so no heat can be transferred into or out of the container. Parts of the graphs of Tvs energy added for the three-phase model are shown to the right. Use these graphs to find the approximate final equilibrium temperatures, Tf iron and Tfwater, the final phases of the iron and water, and the approximate...
