'Latent heat' means heat that is absorbed but does not result in a temperature increase. A good example of latent heat is boiling of water:
H2O(l) + heat = H2O(g)
However, the temperature remains at 100 deg C while water is boiling, so that the heat being consumed is used to vaporize water and not to increase the temperature of the liquid.
Latent heat can be added to the atmosphere by evaporation of water. Since a water molecule contains more heat at a given temperature than an air (N2 and O2) molecule, its presence increases the heat content of the air without changing the temperature.

What role does latent heat play in creating thunderstorms?
Latent heat is the energy that powers a thunderstorm. The latent heat is stored in water vapor, which is in a higher energy state than liquid water. If a warm, moist, unstable parecel of air lis lifted, it will cool and the water vapor in it will condense, releasing that latent heat. This slows the rate of cooling, allowing the air to remain warmer than its surroundings and keep rising on its own bouyancy. It is this rising air, called an updraft, that drives the storm.
Why do most thunderstorms occur on humid days?
Thunderstorms form when warm, moist air rises rapidly and cools, leading to condensation and cloud formation. Humid days provide the necessary moisture in the atmosphere for thunderstorms to develop and fuel their intensity. The high humidity levels help create unstable conditions that support the rapid upward movement of air needed for thunderstorm formation.
How does heat transfer help to setup a hurricane?
Heat transfer is a key driver in the formation of hurricanes as it provides the energy needed to fuel the storm. Warm ocean water heats the air above it, causing it to rise and create low pressure at the surface. This sets off a chain reaction of air movement and water vapor condensation, ultimately forming the intense winds and rains of a hurricane.
How do global air circulation patterns influence development of line thunderstorms in summer?
Global air circulation patterns help create regions of convergence where warm, moist air rises, leading to the development of thunderstorms. In summer, the interaction of these circulation patterns with localized factors like heating from the sun can enhance atmospheric instability, fueling the growth of thunderstorms along boundaries between air masses. This can result in the formation of organized lines of thunderstorms, known as squall lines, which can bring heavy rain, strong winds, and lightning.
How do you find latent fingerprints?
Latent fingerprints can be found using techniques such as dusting, powdering, cyanoacrylate fuming, and ninhydrin. These methods help reveal hidden prints on surfaces by making the ridges of the fingerprint visible for examination and comparison.

How does sunlight help make weather?
What sunlight does is it aids in the development of clouds, and can help with severe weather. What the sun does is it provides latent heat. Latent heat is heat that rises off the ground. If you have ever seen a mirage or a picture of one, than you have seen latent heat. Notice that it looks like waves rising off the ground, that is your latent heat. Hopefully this helped your understanding.
What form of heat transfer helps create a sea breeze?
Two forms of heat transfer help create a sea breeze are conduction and convection. Another form of heat transfer help create a sea breeze is radiation.
How do thunderstorms help your planet?
Thunderstorms help by redistributing heat and moisture around the planet, which can help regulate temperatures and contribute to the water cycle. They also help to break down pollutants in the atmosphere and replenish soil nutrients through lightning strikes.
Latent heat of fusion for ice is 79.8calgram how much ice can be melted with 1000 calories of heat?
To find out how much ice can be melted, divide the total calories of heat by the latent heat of fusion. Amount of ice melted = 1000 calories / 79.8 cal/gram ≈ 12.56 grams Therefore, 1000 calories of heat can melt approximately 12.56 grams of ice.

How do you prevent thunderstorms?
Thunderstorms are a natural weather phenomenon that cannot be prevented. However, early detection systems and meteorological forecasts can help in preparing for and responding to thunderstorms to minimize their impact on people and property.
What processes balance the heat budget of Earth's surface?
Some processes that help balance the heat budget of Earth's surface include radiation from the sun warming the surface, heat transfer through conduction and convection, and the reflection and absorption of heat by clouds and greenhouse gases. The Earth's surface also releases heat back into the atmosphere through processes like longwave radiation and latent heat transfer.

How does newspaper prevent heat loss?
Newspaper can help prevent heat loss when used as insulation. The air pockets within the layers of newspaper trap heat and create a barrier, reducing the transfer of heat through conduction and convection. Wrapping objects or lining walls with newspaper can help retain heat and improve thermal efficiency.
