Are there any substances that conduct heat BETTER than foil or metal? My friend is working on a project and she needs to MAKE a parabolic dish that can boil water in the sun and so far, her group is thinking about using foil, but all the other groups seem to be using foil and they want to use something differentThey can not use bowls (like metal bowls).
in simple terms placed the bottle in a bowl of warm faucet waterthere is not any ought to boil itIf that is getting warm sufficient to burn the baby and you're able to desire to enable it cool, then yeah i could say you run the threat of unfavorable the food, besides the indisputable fact that it quite is a magnificent style of pointless paintingsThe milk would not relatively need to get warm, in simple terms physique temperature, or maybe room temperature if the baby is older and could tolerate it that wayso some distance as whether that is going to wreck food in formulation, it quite is already lifeless, yet i would not prefer to wreck it even extra beneficial.
Basically heat rises to boiling point of around 100 degrees Celsius causing pressure.
The bottom is not completely flat so when the water boils it moves the bowl aroundIt happens to me all the time.
You do nto want a material that conducts heat better, you want a material that absorbs less IR heat and reflects it better if I understand your questionIn fact, you want a material that will conduct heat poorly as you want the heat to be focuse onto a point, not absobed into the mirrorIn reality, to win this contest, bigger is better and so cheaper is better tooCheck the Mythbusters episode summary for the solar collector episodesOne idea for something cheap and different would be to use old (new) CD'sthese seem to collect everywhere and have pretty good reflectivityArrange them on a wooden structure to form a paraboloid surfaceFill the center hole with a patch of aluminum foilYou'll want to make sure you have some sort of mechanism to track the sun so that you make maximum solar powerAstrobuf
