ProfessorFilm condensation occurs when a continuous liquid film forms on a surface during the condensation process, while dropwise condensation occurs when discrete droplets form on the surface. Dropwise condensation is more efficient in heat transfer compared to film condensation due to reduced resistance to heat transfer at the liquid-vapor interface.

What is condensation in science terms?
Condensation is the process by which a gas or vapor turns into a liquid when it comes into contact with a colder surface. This is a fundamental phase change from gas to liquid that occurs in various natural processes like cloud formation and dew formation.
What is the chemical difference between celluloid and cellophane?
Celluloid is a synthetic polymer made from cellulose nitrate, while cellophane is a thin, transparent film made from regenerated cellulose. The main difference lies in their chemical composition, with celluloid being more flammable and prone to deterioration over time compared to cellophane.
What is the distinction between plastic sheet and film?
Plastic sheet is a flat, rigid material with a thickness greater than 0.25 millimeters, while plastic film is a thin, flexible material with a thickness less than 0.25 millimeters. Sheets are typically sturdier and used for applications requiring rigidity and durability, while films are commonly used for packaging and wrapping due to their flexibility.
What is the density of an unexposed processed radiographic film?
The density of an unexposed processed radiographic film is typically very low, as the film has not been exposed to any radiation, resulting in minimal darkening or opacity of the film.
What ingredient makes soap bubble?
Soap bubbles are made of a thin film of water sandwiched between two layers of soap molecules. The soap molecules lower the surface tension of the water, allowing the film to stretch and form bubbles.
