Q2: An Aluminum pot is used to boil water as shown below. The handle of the pot is 20-cm long, 3-cm wide, and 0.5-cm thick. The pot is exposed to room air at 25°C, and the convection coefficient is 5 W/m °C. Can you touch the handle when the water is boiling? (k for aluminum is 237 W/m °C).We can model the pot handle as an extended surface. Assume that there is no heat transfer at the free end of the handle. If a stainless steel handle is used instead of aluminum, what will happen? For a stainless steel, the thermal conductivity k=15 W/m.°C. T 25 °C h=5 W/ m2 °C 100 °C

Distillation

Distillation is a process/technique to separate more volatile components from less volatile components using the principle of relative volatility. In chemical engineering, distillation is one of the most common and important topics that is involved in almost every industry and process.
