Two samples of aluminum foil, 27 grams and 54 grams, are cut out from a roll. which of the following properties is different for the two? a) amount of matter b) color c) density d) electrical conductivity

Amount of matter would be different because density is a constant rate, there would be no colour change as they derived directly from the same metal and the electrical conductivity would not change either. The amount of matter does however, as the two pieces will be of different masses.

Very hard to understand
