Question

Suppose you want to dry your school uniform quickly. Would spreading it near an anghiti or heater help you? If yes, how?

Answer 1

Hint:
Heater or Anghiti is a device that generates heat and the temperature of surroundings is raised. The process of evaporation, in which liquid is converted into a gaseous state, is triggered. To evaporate the liquid molecules, their location must be near the surface, they also need to move in the proper direction, and they should have adequate kinetic energy to surpass the liquid-phase intermolecular forces (forces which take place between atoms).

Complete answer:
Yes, we can dry our uniform quickly if we spread it near an Anghiti or heater. When you will switch on the heater, the electrical energy is converted into heat energy, raising the temperature of the surroundings and ultimately drying up the wet uniform by the process of evaporation.
What is evaporation?
Definition-It is a process of vaporization in which water changes from a liquid to a gaseous/vapor state.
The process of the water cycle includes this term( Evaporation). So, evaporation is a basic aspect of the water cycle. The rays of the sun drive dissipation of water from seas, lakes, dampness in the dirt, and different wellsprings of water. In hydrology, transpiration and evaporation (which includes dissipation inside plant stomata) are all in all named evapotranspiration. Dissipation of water happens when the outside of the fluid is uncovered, permitting atoms to get away and structure water fume; this fume would then be able to ascend and shape mists. With adequate vitality, the fluid will transform into fume/vapors.
How does it take place?
• At the point when the particles of the fluid impact, they move vitality to one another depending on how they crash into one another.
• At the point when a particle close to the surface retains enough vitality or motion to defeat the vapor pressure or equilibrium pressure ( estimate of the ability of a material to change into a vapor state), it will get away and enter the encompassing air as a gas.
• When dissipation happens, the vitality eliminated from the disintegrated fluid will diminish the temperature of the fluid, bringing about evaporative cooling.
Let’s quote a few examples to help it understand better.
• In summers, the temperature of the surrounding is high and so our clothes dry faster as a result of evaporation because the higher the temperature, the higher will be the rate of evaporation.
• In the rainy season and winter season, the air is moist and is saturated hence it takes more time for the clothes to dry.

Note: For the process of evaporation to take place certain factors should be taken into consideration.
• Concentration of evaporating substance
• Rate of flow of surrounding air
• Intermolecular forces
• Temperature of the substance
• Surface area and pressure
Evaporation is considered as an endothermic process in which heat is absorbed.
