What is the latent heat of vaporization of water in J kg?
Table of Contents
For the water substance at 1 atm and 100 °C (the boiling point of water at 1 atm), the latent heat of vaporization is 2.25 ÷ 106 J kg21.
How does latent heat of vaporization influence climate and weather systems?
Growing latent heat flux in the atmosphere increases the amount of clouds, helping retain more heat, which would lead to more evaporation of water and the addition of more water vapor into the atmosphere, which leads to more heat in the atmosphere, and so on, in a positive feedback cycle.
What is latent heat How does latent heat contribute to storm systems?
Latent heat causes hurricanes to intensify. Air heats as it crosses warm water and picks up water vapor. As the vapor condenses to form clouds, latent heat is released into the atmosphere. This added heat warms the air, producing instability and helping clouds to rise and the storm to intensify.
Why is latent heat of vaporization important for weather?
(4.5) The latent heat of vaporization, released when lifted water vapour condenses in the upper atmosphere, is a key contributor to the development of weather systems. It also provides a cooling effect when water evaporates.
What is the latent of vaporization of water?
For example, the latent heat of vaporization of water is 540 cal/g and the latent heat of freezing of water is 80 cal/g.
When water vapor condenses into liquid How is latent heat transferred?
Latent heat of condensation is energy released when water vapor condenses to form liquid droplets. An identical amount of calories (about 600 cal/g) is released in this process as was needed in the evaporation process. This is one mechanism of how thunderstorms maintain their intensity.
What is the role of latent heat in thunderstorms and other severe weather events?
Thunderstorms release enormous amounts of latent heat which adds to the instability in the atmosphere causing some thunderstorms to become severe. In hurricanes, latent heat is released within the clouds of the hurricane, warming the air inside the clouds.
How does water’s latent heat influence the ocean?
A large amount of heat is transferred to the atmosphere in the process of condensation, because of the latent heat of vaporization. Evaporation and precipitation also affect the patterns of water density on the surface of the ocean, which are inseparably tied to ocean circulation.
How does the latent heat of water fuel the formation of storms?
When the surface water is warm, the storm sucks up heat energy from the water, just like a straw sucks up a liquid. This creates moisture in the air. If wind conditions are right, the storm becomes a hurricane. This heat energy is the fuel for the storm.
How do you calculate latent heat and sensible?
The easiest way to find latent Btu is to subtract delivered sensible Btu from the delivered total Btu. A simple formula to find latent Btu is total Btu minus sensible Btu.
