what is a cell .?
GIA
MAGNETIC
To roughen a smooth surface, shape a surface, or remove surface contaminants. i.e. to remove paint from a vehicle.

A computer hard disk drive stores and retrieves data efficiently by using magnetic storage technology. Data is written onto the disk using a magnetic head that creates tiny magnetic fields on the disk's surface. To retrieve data, the head reads the magnetic fields and translates them into digital information. The disk spins rapidly, allowing the head to access different parts of the disk quickly. This process enables the hard drive to store and retrieve data in a fast and efficient manner.
earths surface
A larger surface area provides more space for water molecules to escape into the air, increasing the rate of evaporation. This is because there are more molecules at the surface exposed to the air, leading to more rapid evaporation compared to water with a smaller surface area.
Subsurface geology
Charcoal effectively absorbs odors through a process called adsorption, where odor molecules are trapped on the surface of the charcoal. The porous structure of charcoal provides a large surface area for odor molecules to adhere to, removing them from the air and reducing the smell.
Water molecules can evaporate from the surface of water, where they gain enough energy to overcome surface tension and escape into the air. Below the surface, water molecules can also evaporate through a process known as sublimation, where molecules transition directly from a solid to a gas, although this is less common.
Activated charcoal effectively removes odors by adsorption, which is the process of trapping odor molecules on its porous surface. The porous structure of activated charcoal provides a large surface area for odor molecules to adhere to, effectively trapping and removing them from the air.
Increasing the surface area exposed to the surrounding environment can increase the rate of evaporation because more liquid molecules are exposed to the air, allowing for a faster transition from liquid to vapor. This is because a larger surface area provides more space for the liquid molecules to escape into the air as vapor.
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
A scanning tunneling microscope allows scientists to see individual atoms and molecules on a surface by measuring the electrical current that flows between the microscope's probe tip and the sample surface. This technology provides high-resolution imaging of surface structures, enabling the visualization of atomic-scale details.
The workfunction table provides information about the minimum amount of energy needed to remove an electron from a material's surface, known as the work function.
The inward force among the molecules of a liquid is known as cohesive force. It is responsible for keeping the molecules together and creating surface tension in the liquid.
The globe cuz all it shows is the earth and its contenents no mountains or lakes.
