Hi,
Every element in the universe is made of its own properties which determines its weight, strength,and other features like ductility, meliability, flexibility it is mainly determined by its atomic structure
when it comes to weight, the constant weight given is same for all elements, like 1 kg of cotton and 1 kg of iron weighs the same,but the quantity may vary for different elements depending on the weight.
Thanks

AT first you will think 1 kilo of iron is heavier than 1 kilo of cotton. But come to think of it, they are both 1 kilo. =) They are both the same weight. =)

plz think about the chemical nature of the cotton and iron
When the 1 kg of cotton fabric is heated, the molecules are more easily reoriented. In the case of cotton fibers, which are derivatives of cellulose, the hydroxyl groups that cross-link the cellulose polymer chains are reformed at high temperatures, and become somewhat "locked in place" upon cooling the item. In permanent press pressed clothes, chemical agents such as dimethylol ethylene urea are added as cross-linking agents.
Thus due to the locking of the cellulose polymer, the cotton becomes solid. hence looks like iron. hence the "Density" and "Specific Weight" remains same. The ironing temperature of cotton is 180–220 °C.
