aluminumthe student puts the blocks into a beaker of boiling waterThe blocks remain in boiling water until each block is as hot as it going to getThe blocks are then removed and a thermometer is immediately inserted into each other.ahow will the thermometer readings compare?bwhich block reached its final temperature most quickly?
Well, the higher the energy the more penetration they Xrays themself will haveA low energy Xray can be stopped by the aluminum, and a high energy Xray can zip right thru it- in fact, Gamma radiation will fly right thru an airplane while in flight- it won't even take time to use the bathroom, read a magazine or even pinch a nice stewardess on the butt before it leavesRepeated bombardment of SOFT Xrays will result in weakening the metal, given time- they impact the atoms center and break it apartHard Xrays just zip right on thru- to much energy and they pass right around themWith aluminum you're more concerned with oxidation and vibration cracks than you are instead of radiation damageIn fact, you can take a brand new float airplane, land it in salt water and the price of the aircraft just dropped by 50% due to corrosion
As with any element, aluminum will absorb x-rays of specific energies, and re-radiate x-rays of lower energyThe disturbing of the electrons can cause disruptions in the crystal structure of the aluminum, weakening it, but it would take a truly intense blast of radiation for this effect to become noticeable.
they will all read 100C, or close to italuminum has twice the specific heat of iron, so if it is the same shape and size of the 100g iron block, it will take twice as long to warm upBut because the density is a lot less, the aluminum block will be larger You need the shape and size of the three blocks and you need to calculate the thermal conductance of eachNot an easy calculation .
