Respuesta :
4. Blue, Red, Green, Purple
(Lowest densities on the top, highest densities on the bottom)
(Lowest densities on the top, highest densities on the bottom)
The liquids will arrange themselves in the order; purple, green, red, blue.
Density is defined as the mass per unit volume of a substance. Usually, in a mixture of liquids, the liquid with lower density is found at the top while liquids with higher densities are found below.
In this problem, we know the following;
Density of red liquid - 1.2 grams per centimeter cubed
Density of blue liquid - 1.6 grams per centimeter cubed
Density of green liquid - 0.8 grams per centimeter cubed
Density of purple liquid- 0.1 grams per centimeter cubed
The liquids will therefore arrange themselves in the order; purple, green, red, blue.
