What occurs after condensation?
After Water Condenses Some of the water vapor in the atmosphere that condenses is stored in clouds. Clouds are more likely to form when the air is humid and contains more water vapor. The energy released when gaseous water vapor condenses to form liquid water droplets is called latent heat.
What is condensation and its types?
Dew: the water droplets formed by condensation of water vapor on a relatively cold surface of an object. It forms when the temperature of an object drops below the dew point temperature.
How do you measure condensation?
Based on the definition, a simple method to measure the dew point temperature involves cooling a surface until water vapor begins to condense on the surface. This is the principle used in a chilled mirror hygrometer, which is used to measure the dew point.
What time of day does condensation occur?
Dew point is the temperature at which condensation happens. (Dew is simply condensed water in the atmosphere.) Air temperatures can reach or fall below the dew point naturally, as they often do at night. Thats why lawns, cars, and houses are often coated with water droplets in the morning.
At what humidity does condensation occur?
100%
Why latent heat is released during condensation?
Latent heat of condensation is energy released when water vapor condenses to form liquid droplets. The temperature does not change during this process, so heat released goes directly into changing the state of the substance.
What is the formula for latent heat of vaporization?
Latent heat calculation The specific latent heat is different for solid to liquid transition and liquid to gas transition. For example, if we want to turn 20 g of ice into water we need Q = 20 g * 334 kJ/kg = 6680 J of energy. To turn the same amount of water into vapor we need Q = 45294 J .
What is the latent heat of vaporization of ethanol?
896 385
What is specific latent heat of vaporization formula?
The specific latent heat (L) of a material… is a measure of the heat energy (Q) per mass (m) released or absorbed during a phase change. is defined through the formula Q = mL.
What is meant by specific latent heat of vaporisation?
Each substance has two specific latent heats: latent heat of fusion (the amount of energy needed to freeze or melt the substance at its melting point) latent heat of vaporisation (the amount of energy needed to evaporate or condense the substance at its boiling point)
