Film 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 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 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 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.
Difference between film and drop wise condenation?
Film condensation occurs when a continuous film of condensed liquid forms on a surface, while dropwise condensation occurs when individual droplets of condensed liquid form and coalesce on a surface. Dropwise condensation is more efficient than film condensation in terms of heat transfer, but it is more difficult to achieve and maintain in practice.
High heat transfer coefficient film-wise condensation or drop-wise?
In dropwise condensation about 5-8 times higher coefficient than filmwise.
What is the difference between Drop wise condensation and film wise condensation?
heat transfer rate high
What is the difference between silent film and sound film?
The difference between silent film and sound film is because that silent film has no sound whatsoever and a sound film has sounds in it
What is difference between thick and thin film resistor?
Difference between thick and thin film resistor is not related to thickness but its based on how the film is applied to the surface.
Difference between thick and thin film integrated circuits?
they have differe.nt method of deposition of film of conducting material. Hence, the difference between two is their fabrication process.
What is the difference between a feature film and a supporting feature?
there the same
What is the difference between a digital film and just the regular film?
A digital film is stored and played from a hard drive. Technically its not film at all.
What is the difference between novel holes and the film of holes?
There is no difference, in the movie they used the same dialogue as they did in the book.
What is the difference between indie film and local film?
An indie film simply isn't supported by a production company but it can still be widely available.
What happens when water vapour touches the mirror?
When water vapor touches a mirror, it condenses into liquid water due to the temperature difference between the vapor and the mirror surface. This condensation creates a thin film of water droplets on the mirror's surface, causing it to appear foggy or misty.
What are Circuit diagrams for thin film transistor and thin film capacitor?
the main difference between the thick film and thin film ics is the method of deposting the layer but not the relative thickness........................
