Condensation and evaporation are two very important phenomena. We keep experiencing it in our daily life. Evaporation and condensation both refer to a phase change between the vapor and liquid phases. The main difference between evaporation and condensation is that evaporation involves a phase change from the liquid phase to the vapor phase at a temperature below the boiling temperature of the liquid. But condensation involves a phase change from vapor to liquid phase.
He is used to explain the phenomena surrounding cool drinks like rain clouds, water droplets. Evaporation and condensation have a wide variety of applications in fields such as analytical chemistry, industrial chemistry, process engineering, thermodynamics, and even medical science. It is important to have a good understanding of those events. Because have good understanding in their applications. In today’s article, we are going to tell his understanding.
Difference Between Evaporation and Condensation
|Evaporation occurs on all surfaces.||Evaporation is observed when the air is dry and warm. When the temperature drops below the saturation level, condensation occurs.|
|Evaporation occurs only at the surface of the water.||Condensation occurs on cold surfaces.|
|Evaporation is defined as the process in which a liquid or gas turns into water.||Condensation is defined as the process in which a gas transforms itself into water droplets.|
|Energy is consumed during the process of evaporation.||During the process of condensation, energy is released.|
|Evaporation is a type of evaporation.||There are four types of condensation, dew, fog, cloud and frost.|
|Evaporation occurs before any liquid reaches the boiling point.||In condensation, the phase changes regardless of temperature.|
What is Condensation?
Condensation is that process. In which atmospheric water vapor changes into water or ice particles. It is the exact opposite process of evaporation. When the temperature of a saturated air falls below the dew point. So that air cannot hold as much moisture in itself as it was holding earlier. The excess amount of moisture in the form, depending on the temperature (at which condensation occurs), turns into tiny water droplets or ice particles.
Condensation then occurs. when the air temperature drops. This reduces the amount of water vapor present in the air. So the water molecules clump together to form liquid droplets. During condensation the material in the vapor phase undergoes a phase change to become a liquid. It happens then. When air reaches the maximum saturation level for a gas. The maximum saturation level of water molecules in the air can be reduced by lowering the temperature or increasing the pressure.
Examples of Condensation
- Steamy mirrors
- Fog in the air
- Water droplets on windows
- Morning dew
What is Evaporation?
Evaporation is the phase change of a liquid to a gas state. Evaporation is one of two types of evaporation. Another form of vaporization is boiling. Evaporation occurs only at the surface of the liquid. When the energy of such a surface liquid molecule is increased due to any internal or external factor, the molecule will be able to break the intermolecular bonds acting on it, thus forming a gas molecule.
This process can occur at any temperature. Common sources of evaporative energy are sunlight, air or environmental temperature. The rate of vaporization of a liquid depends on these external factors as well as some internal factors of the liquid. Intrinsic factors such as the surface area of the liquid, the intermolecular bond strength of the liquid, and the relative molecular mass of the object affect the evaporation of the liquid.
Examples of Evaporation
- Whistling of Kettle
- Drying of a mopped floor
- Spraying of deodorant on body
- Rise in temperature
- Moisture loss
- Wind speed
What is the Difference Between Evaporation and Condensation
- Evaporation is a process in which water turns into vapor.
- Condensation is the opposite process where water vapor converts into smaller droplets of water.
- Evaporation occurs before a liquid reaches its boiling point.
- Condensation is a phase change regardless of temperature.
- When the liquid is heated or when the pressure is lowered, the force of attraction between the molecules is less.
- The liquid then evaporates into a gas.
- When the gas is cooled or when the pressure is increased, the forces of attraction between the molecules become stronger.
- The gas then condenses into either a liquid or a solid.
- Evaporation can occur on all surfaces, at all times and in all places.
- Evaporation often occurs when the air is dry, hot and windy.
- When the air temperature falls below the saturation level.
- Condensation takes place on salt, hygroscopic nuclei – pollen particles, carbon particles, etc.
