What comes first condensation or evaporation?
Evaporation is the change of state of water (a liquid) to water vapor (a gas). Condensation is the process where water vapor (a gas) changes into water droplets (a liquid). This is when we begin to see clouds.
What is lost during the process of evaporation?
Transpiration is loss of water in vapor form, from living plant cells thus it is a physiological process while evaporation is loss of water from any free surface in vapor form, thus it is a physical process.
What causes the evaporation rate of water to increase?
When water temperature increases (right), the rate of evaporation also increases. In turn, the amount of water vapor in the “air space” above the water increases. The increase in water temperature causes the evaporation rate to increase and, for a time, net evaporation occurs.
How do you calculate evaporation speed?
What is the formula for evaporation rate of water? [closed]
- gh=ΘA(xs−x)
- gh = amount of evaporated water per hour (kg/h)
- Θ=(25+19v) = evaporation coefficient (kg/(m2 h))
- v = velocity of air above the water surface (m/s)
- A = water surface area (m2)
What are the factors that affect rate of evaporation?
Factors That Affect the Evaporation
- Temperature: As the temperature increases, the rate of evaporation also increases.
- Surface area: As the surface area increases, the rate of evaporation increases.
- Humidity: The rate of evaporation decreases with an increase in humidity.
What is the effect of temperature and surface area on evaporation?
Evaporation increases with an increase in the surface area If the surface area is increased, then the amount is of liquid that is exposed to air is larger. More molecules can escape with a wider surface area.
Does evaporation depend on surface area?
The rate of evaporation depends on the liquid’s exposed surface area (faster when increased), the humidity of surroundings (slower when increased), the presence of wind (faster when increased) and the temperature (faster when increased).
