The discharge of a liquid from a surface, such as pores or incisions, is known as seepage. Seepage can occur naturally through porous materials like soil, rock, or concrete, as well as through engineered structures like dams or retaining walls. It is important to manage seepage to prevent erosion, instability, or damage to surrounding areas.
Surface discharge of liquid waste typically requires obtaining permits from the appropriate regulatory agencies, adhering to strict guidelines on the type and amount of pollutants that can be discharged, and implementing measures to prevent harm to the environment and public health. Monitoring and reporting requirements may also be necessary to ensure compliance with regulatory standards.
Surface Tension
When a liquid is poured into a graduated cylinder, its surface forms a meniscus due to the interplay of cohesive and adhesive forces. The liquid tends to cling to the walls of the cylinder, causing the surface to curve upward at the edges. This curvature can be concave or convex, depending on the liquid and the cylinder material, but for most liquids like water, it is usually concave. The height of the liquid at the meniscus is used for accurate measurements.
Before a liquid appears on a surface, the molecules of the liquid are typically attracted to each other due to cohesive forces. As the liquid is introduced to the surface, it spreads out or forms droplets depending on the surface tension and the adhesive forces between the liquid and the surface. The interactions between these forces determine whether the liquid will wet the surface or bead up.
The bubble is called a meniscus. It is caused by surface tension, and usually appears as a curved surface at the top of the liquid in the test tube. To accurately measure the volume of liquid, the measurement should be taken at the bottom of the meniscus.
Coefficient of discharge of an ideal liquid can be defined as a ratio of actual discharge and theoretical discharge. where, Cofficient of discharge = Actual Discharge/ Theoretical discharge.

liquid like water. Edit : It's hard to say where the atmosphere ends and the "surface" begins. Scientists usually say the surface is gas with liquid and various "ices" in the next layer.
This phenomenon is called evaporation.
It is called discharge.
Mosquito bites discharge a clear liquid because that is their numbing fluid. This is what makes the bite nearly painless.
Surface Tension
Surface tension acts perpendicular to the surface of the liquid, attempting to minimize the surface area and causing the liquid to form into droplets or exhibit a meniscus in a container. This force is due to the cohesive forces between the liquid molecules at the surface.

Evaporation is the type of vaporization of a liquid that occurs only on the surface of a liquid.
The liquid particles gain energy (usually from thermal energy, i.e. heat) and start to get "excited." This means they vibrate and eventually break away from the surface of the liquid and into the surrounding gas. This particle of matter is still present, but not in liquid form.
