Color is most easily observed property of minerals but it is the least useful property for identification list two reasons why this is true and give one example for each?

Answer 1) The color of minerals (especially gasses) can change depending on the concentration of said mineral. The more diluted a mineral, the weaker or more washed the color will appear, which can change it's properties 2) The color of a mineral can also be disturbed by impurities. Diamonds come in all kinds of colors because of microscopic differences within their individual constructs 3) (just for fun) While "RED" and "BLUE" are univerally understood, "AQUAMARINE" and "CHARTRUSE" can be relative to the person, making them non-absolute.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
