Answer:
cylinder A has a higher density then cylinder B or more accurately the liquid in cylinder A is denser then the liquid in the second tube.
Explanation:
"Denser" simply means more matter is contained in the same space for example say you fill a tank with helium and another tank with water. Although they are the same size one will weigh much more because their is more particles or "stuff" inside the same area this can be because of a few things one it can be because the atoms or elements that compose the substance are heavier containing more electrons and protons in their orbit. or the molecular structure is more compact like a chicken wire fence has more wire in it then a barbed wire wire fence covering the same area because of the grid of wire in the middle.
It would be considered a Homogeneous Mixture. A mixture with two or more components mixed evenly is a Homogeneous mixture.
