We explain that what are examples of condensation? with definition, types and uses to better understanding. So lets read…
Definition of Condensation
Condensation is the physical change in which water goes from vapor to liquid . It happens when hot particles touch a cold surface, and on contact they release their heat , transforming into liquid water on top of said surface. This phenomenon is the one that forms the clouds and later the rain.
Condensation is also what we observe when a translucent layer forms on the outside of a glass container, which contains a cold drink inside. That thin layer that is blurred on top of the glass is the water vapor present in the environment, which has condensed in the glass. what are examples of condensation
Condensation involves a transfer of energy , which goes from the hot steam to the cool surface. This energy delivered is called the enthalpy of condensation and is represented as ΔHc. Its value depends on the absolute pressure at which the steam is, and can be consulted in tables of thermodynamic manuals.
When the enthalpy of condensation has left the steam, it will turn into a liquid. The liquid is going to be at the same temperature , because it has only changed phase. It is from there that it can begin to cool down. what are examples of condensation
Types of Condensation
Condensation, as a phenomenon that occurs on surfaces, will be of two types: what are examples of condensation
- Film condensation
- Drip condensation
1. Film condensation
In film condensation, the vapor reaches the cold surface and forms a translucent layer or film , dulling the exterior of the container. In this type of condensation it will occur that the water particles will cover the entire area, adhering to the material, and will not leave room for more steam to be transformed.
2. Drip condensation what are examples of condensation
Drip condensation is that in which the vapor reaches the surface and is delivering its energy, turning into liquid in the form of drops that will slide to give way to more vapor. It is the most efficient type of condensation, because it leaves the contact surface free for more heat transfer and thus allows more steam to condense.
Uses of Condensation what are examples of condensation
Condensation is used in industrial evaporation processes. Evaporation involves releasing water from a dilute aqueous solution. When this process is carried out in an industrial plant, it will participate in two parts:
During the heating of the dilute solution, which is the raw material, saturated steam is going to be introduced through a pipe , that is, it is at the critical point about to condense, and when it transmits its enthalpy of condensation, it will deliver to the diluted solution an enormous amount of heat. This heat is what will make it evaporate more easily.
In this way, water will be released in the form of steam from the raw material. This steam will be conducted by means of a vacuum to a condenser, which is a tank that has a coil with cold water inside. The cold coil will receive the steam that comes from the raw material, and it will convert it into water, which can then be reused for other processes.
Examples of Condensation
- The film that forms around glasses with cold soda.
- The drops that form on the walls of a sauna.
- Films that form on windows when the interior of the home is hot and the exterior is icy.
- The mists, due to the decrease in the temperature of the air in contact with the cold air.
- Clouds, which are volumes of air that become visible because they contain many tiny drops of water and ice crystals.
- The shower door has condensation when we shower with hot water.
- The oven window when a cake is being prepared and it has ingredients with high water content.
- A film of condensed water forms on the lid of a closed glass refractory due to the steam from hot food.
- A film of condensate forms on the glass of cold drink bottles.
- On the inside of a car’s windows, which are usually warmer, a layer of condensate forms on rainy or cold days.
