how much heat can aluminum withstand
Substances that allows the flow of heat energy through it are known as good conductors of heat energy. Most metals are good conductors of heat energy. Most nonmetals are not a good conductors of heat energy. Interestingly, the best metal at conducting heat is silver, which is slightly better than copper, but it is nowhere nearly as good as diamond, which can conduct heat as much as five times as well, and is not a metal. Go figure.
You question is very poorly worded, It is difficult to tell what it is you want to know. On the simple basis the heat of Aluminum would depend on it mass and how much energy you put into it - )how much you have heated it) On a more precise basis the figure below will tell you how much energy you need to put into it to heat it up: The specific heat of Aluminum is 0.91 kJ/kg oK
Aluminum is a commodity, therefore the price is dependent on the stock market.
Well lets go through the checklist for metals. Metals have several properties:MalleableHave Luster (shiny)Solid at room temp (Mercury is a notable exception to this)High melting/boiling pointsAluminum fits all four of these to a T making it very much a metal.
Elemental boron (as compared to bornon compounds) is a metal, which looks much like aluminum.
Copper and aluminum. Most heat sinks are made of Aluminum (cheap and a good conductor of heat).
heat is the byproduct of an object vibrating at the molecular level. When those vibrations transmit to nearby collision molecules, heat transfer occurs. Generally, the less a metal weighs, the quicker it can transfer heat. Aluminum is a good example of this. But a hot aluminum pan will warp easily if you put cold water on it. Cast iron transfers heat much slower and doesn't easily warp if you douse it with cold water

Aluminum is a metal for one thing, but yes, the density of aluminum is far less than lets say, Steel.
How much heat (in calories) is required to heat a 43 g sample of aluminum from 72 F to 145F

That depends on what you are trying to ask.First point is that heat is energy in transit - if it isn't moving from one place to another it's technically not heat. Thermal energy - the energy held by a mass due to temperature is a better term, but even that is a bit ambiguous.With that in mind...if you mean how much energy can be stored as thermal energy by aluminum, you would have to look up the heat capacity - which is approximately 0.91 kJ/kg K (the exact value depending on temperature and purity of the aluminum)If you mean how much resistance aluminum foil can provide to the transfer of heat, that would depend on the temperature gradient and how shiny the aluminum was - shiny aluminum will reflect more heat that dull/burnished aluminum surfaces.

This means that copper will not absorb the heat from the water as much as the aluminum. Aluminum will "steal" more heat from the water- which you do not want. You need the heat to stay with the water until it serves its purpose.
The two are highly reactive when mixed in water. If you add aluminum to a water solution of copper chloride, the aluminum will be combined as aluminum chloride gas, releasing the copper into the water. The mixture will turn very hot, bubble up, and start to smoke, and the color will change from blue to dark red. ========================= The first sentence is correct, the two are highly reactive, but from there on, there are problems... There's no such thing as aluminum chloride gas. There is a gas given off, but it is hydrogen gas. The "smoke" is actually tiny droplets of water condensed from water vapor. It gets that hot. The red color is due to the formation of copper metal a Cu2+ ions are reduced to the metal as aluminum metal is oxidized. Aluminum metal has a thin coating of aluminum oxide, Al2O3, covering the surface. Even freshly scraped aluminum metal will quickly reform the passivating layer of aluminum oxide. So in many solutions, the layer of Al2O3 prevents any aluminum metal from reacting. If aluminum metal is placed in a solution of copper(II) sulfate, you will not get a reaction. No copper metal will form on the aluminum. But when placed in copper(II) chloride, aluminum will give a vigorous reaction with a lot of heat and hydrogen gas being given off. The reason is the chloride ion. In the presence of chloride ion, the Al2O3 layer dissolves forming the AlCl4^- in solution and exposing a fresh layer of aluminum metal. The aluminum metal will reduce copper(II) ions to copper metal, AND the aluminum metal will react with water very much like an alkali metal reacts with water, vigorously, with a lot of heat given off, and with the formation of hydrogen gas. Al2O3 + 8Cl- + 3H2O --> 2AlCl4^- + 6OH- Al(s) + OH- + 2H2O --> Al(OH)3(s) + H2(g) 2Al(s) + 3Cu2+ --> 2Al3+ + 3Cu(s)
yes, if there is not enough water the heat will be affected because not as much heat can be held.
