Answer:
The greater the inter molecular forces in a substance the greater the attraction the molecules of the substance have for other molecules.
Because the molecules in liquid A have a greater attraction for each other the molecules in liquid A will "stick" together more than the molecules in liquid B.
The more the molecules "stick" together the greater the viscosity.
Radon is colorless at standard temperature and pressure and it is the most dense gas known. At temperature below it's freezing point is has a brilliant yellow phosphorescence. It is chemically nonreactive, it is highly radioactive and has a short half life.
The image shows a phospholipid bilayer. Macromolecules that make up most of the structure that is shown are proteins and lipids. Lipids can make up 20% to 80% of the membrane depending on the location and type of the cell. The rest is made up of proteins.
