Curved surface of a liquid?
Meniscus
What is the tendency of liquids to decreases their surface area to the smallest size possible?
The surface area of the liquid can decrease when there is increase in the temperature of the day,what is called evaporation is been taking place in the surface of the liquid,wchich decreases the liquid area.
Calculation of contact angle?
Angle of contact is the angle between a tangent to the liquid surface at the interface and the solid surface inside the liquid. For concave surfaces, it is acute . For convex surface , it is obtuse.
Why does a liquid have a flat surface?
A liquid has a flat surface due to the balance of cohesive forces between its molecules and the gravitational force acting on it. Cohesive forces pull the molecules together, minimizing surface area and creating a flat surface, particularly in a container. The gravitational pull ensures that the liquid settles into a stable shape, typically resulting in a horizontal surface when at rest. This phenomenon is also influenced by the container's shape and the liquid's properties, such as viscosity and surface tension.

What are the different types of chromatography?
there are different types like gas chrom. and thinlayer chrom Answer: There are two types of chromatography:liquid chromatography gas chromatography
What is the difference between partition chromatography and adsorption chromatography?
The partition chromatography involves separation between liquids while adsoption chromatography involves solid and liquid separations. Answer: Partition Chromatography is a liquid liquid extraction which involves two solvents while adsorption chromatography is a liquid solid extraction which involves a solid stationary phase & a liquid mobile phase.

What are 3 types of chromatography?
1. thin -layer chromatography 2. gas chromatography 3. liquid chromatography
What is the force of attraction between the molecules of a liquid that are below the surface which creates an inward pull?
The force of attraction between molecules below the surface of a liquid is called cohesive force. This force creates an inward pull, causing the liquid molecules to stick together and form a well-defined surface.

Why do molecules at the surface of a liquid behave differently from molecules in the interior of the liquid?
In the interior the intermolecular forces of attraction is equal in all directions but the molecules at the surface of liquid experiences unequal intermolecular forces of attraction. the molecules at the surface are free so the adsorb liquid or gaseous molecules

How can lower surface tension be achieved in a liquid solution?
Lowering surface tension in a liquid solution can be achieved by adding surfactants or substances that reduce the attraction between molecules at the surface of the liquid. This disrupts the cohesive forces and allows the liquid to spread more easily.
