What most accurately describes surface tension? A) Water molecules on the surface of the liquid are not surrounded by water molecules on all sides and experience uneven repulsion forces. This outward force prevents molecules on the surface of the liquid from moving inward.

B) Water molecules at the surface of the liquid form hydrogen bonds with molecules in the air, limiting their mobility and creating a skin on the surface of the liquid.

C) Water molecules on the surface of the liquid are not surrounded by water molecules on all sides and experience uneven attraction forces. This inward force causes molecules on the surface of the liquid to be pulled inward.

D) Water molecules at the surface of the liquid are attracted to molecules in the air by covalent forces, creating a skin on the surface of the liquid.

High-pressure liquid chromatography (hplc) is a method used in chemistry and biochemistry to purify chemical substances. the pressures used in this procedure range from around 500 kilopascals (500,000 pa) to about 60,000 kpa (60,000,000 pa). it is often convenient to know the pressure in torr. if an hplc procedure is running at a pressure of 1.03×108 pa , what is its running pressure in torr?
