👉 In physics, a cover slip is an element of a liquid or gas that acts as a barrier between two surfaces. It can be thought of as a surface with a small hole in it. This phenomenon occurs when a liquid or gas is forced to flow through a narrow channel or gap between two surfaces, and the resulting pressure difference causes the liquid to flow over the wall.
Cover slips are important for several reasons:
1.
Thermal Conduction
: Cover slips can help regulate the temperature
