Gold melts at 1064.43° Centigrade. It can conduct both heat and electricity and it never rusts.
Gold is very flexible metal and can be stretched out to 80 to 90 km per ounce.
1 ounce =28.34 gram approx
Taking the average of the distance gold can be stretched per ounce =(80+90)/2=85
so 1 gm = 85/28.34 =2.99 km approx
We can say that one gram of gold can be stretched anywhere between 2.99 to 3 km approx
