Want this question answered?
galvanised steel is a lot more safer....... if u go by the book.... it is upto 10 times stronger than stainless steel in aluminum
Aluminum is higher expansion - about 23 ppm/C, whereas steels range from 12ppm/C for alloy steel and carbon steel, 17 ppm/C for stainless 300 austenitic series, and 11 ppm/C for stainless 400 martensitic series
When compared by volume, copper is best, then aluminum and finally iron. When compared by weight, aluminum is better than copper. You have to compare by volume because aluminum is so much lighter than copper, an aluminum wire that weighed the same as a copper wire would be much bigger and harder to work with.
compare between planned and unplanned change
You can't compare the two.

According to wikipedia its Mohs hardness is 2.0 and it Brinell hardness is 203 MPa. Compare with aluminum for which the figures are 2.75 and 245 respectively.

what type of breakage is more common deavage or fracture
Copper is good conductor of heat as compare to stainless steel. Hence it (Copper) can heat early as compare to stainless steel. Thats why, use of utensils having copper bottoms requires less time for cooking.
by not being stupid and comparing the two items
You start by scratching it and seek it's hardness. When you find its hardness, compare it to another mineral with the same hardness. If they look exactly the same, and have the same arrangements of minerals, then they are the exact same mineral.

oof
Minerals are tested for hardness by performing a scratch test. The unknown mineral is scratched with another object that the hardness is known. For example, a unknown mineral may be scratched with a piece of metal to compare the resistance.

The same.
