This is a question our experts keep getting from time to time. Now, we have got the complete detailed explanation and answer for everyone, who is interested!
The production of water from the condensation of steam results in the release of heat.
When steam cools down and becomes water, does the process absorb or release heat?
The formation of liquid droplets from water vapor results in the release of an amount of energy known as latent heat of condensation. This procedure burns the same number of calories—approximately 600 calories per gram—that were required for the previous process, which involved evaporation.
When steam cools down and condenses, what happens?
Ice is formed when water in its liquid state freezes and becomes solid.
Is that steam that we see?
In contrast to water vapor, which may be seen as a mist or fog, steam is an odorless and colorless gas…. When you first look, there appears to be nothing there; this is due to the steam. The steam is followed by the little white billows of smoke, which are actually the steam re-condensing into water vapor.
Is condensation demonstrated by steam as an example?
The transformation of water vapor into liquid water is referred to as condensation, and it occurs when water vapor in the air… The transformation of the liquid into gas is demonstrated by the appearance of steam, which is another name for water vapor, as well as bubbles in the pot of water that is boiling.

How come burns from steam are more severe than those caused by boiling water?
Because steam has more heat vitality than water due to the latent heat of vaporization, steam will generate a greater burn than boiling water will…. Because steam is produced from water that has been brought to a boil, it contains both the active heat energy of the boiling water and the latent heat energy of the vaporization process.
What is meant by the term “latent heat of vaporization” when referring to water?
The heat required to vaporize one kilogram of water is approximately 2,260 kilojoules, which is equivalent to 40.8 kilojoules per mole. The process of vaporization is the antithesis of the condensation process. The heat of condensation is the heat that is emitted when one mole of the substance condenses at its boiling point under standard pressure. This occurs when the temperature of the substance is maintained constant.
When water condenses, what byproducts are released?
The transformation of water vapor into liquid water is referred to as condensation, and it occurs when water vapor in the air… It is possible for these clouds to generate precipitation, which is the major path that water takes to make its way back to the surface of the Earth as part of the water cycle.
Condensation—does it result in the release of heat?
The heat that is produced as a result of the condensation of one mole of the substance is referred to as the latent heat of condensation. Since there is no change in temperature during this process, the heat that is generated contributes directly to the transformation of the condition of the substance… The term “heat of condensation” refers to the form of energy that is produced by this process.
Which of the following best illustrates the phenomenon of condensation?
1. If you drink a cold Coke while it’s hot outside, the can will “sweat.” After colliding with the cooler surface of the can, water molecules that were previously in the air as a vapor condense into water droplets. 2. In the morning, dew can be found on grass and leaves because the warmer air deposits water molecules on the cooler surfaces of the leaves and grass.
How much energy is created when a liquid boils to the point where it vaporizes?
When one mole of water at 100 degrees Celsius and one atmosphere of pressure is turned into one mole of water vapor at 100 degrees Celsius, 40.7 kilojoules of heat are taken in from the surrounding environment. When 1 mole of water vapor at a temperature of 100 degrees Celsius cools down to become liquid water at the same temperature, 40.7 kilojoules of heat are given off into the environment.
Example of what is meant by the term “latent heat of vaporization”
For instance, if a pot of water is kept boiling at a temperature of 100 degrees Celsius (212 degrees Fahrenheit), the temperature will remain at that level until the very last drop evaporates. This is because all of the heat that is being added to the liquid is absorbed as latent heat of vaporization and carried away by the molecules of escaping vapor….
Why is it vital to consider the latent heat of vaporization of water?
If you want to totally separate the molecules, moving from liquid to gas, you will need a far higher amount of energy than if you merely want to lessen their separation, which will result in solid to liquid. As a consequence of this, the latent heat of vaporization is significantly higher than the latent heat of fusion.
How is it possible to extract the latent heat from water?
The computation of latent heat
The specific latent heat is calculated differently for the transition from solid to liquid and the transition from liquid to gas. For instance, if we wish to change 20 grams of ice into water, we will need Q = 20 grams multiplied by 334 kilojoules per kilogram, which equals 6680 joules of energy. We require Q equal to 45294 J in order to convert the same quantity of water into vapor.
Why are steam burns so much more painful?
Because of the latent heat of vaporization, burn injuries caused by steam are more likely to occur than those caused by boiling water. When water changes from its liquid state to its gaseous state, it can expand to nearly 1,600 times its original volume. As a result, steam can frequently break free of its container, even when the container is pressurized.
Why are burns caused by steam so severe?
The reason for this is that the phase change that causes the burning sensation on your skin is also caused by steam. It reverts back to the state of water. The transformation from a gas to a liquid is an essential process. When steam comes into contact with your skin, it immediately cools down, so transferring some of its energy to you, and then transforms back into a liquid state.
How is it that steam burns are more severe than those caused by boiling water or steam Class 9?
Although though both steam and boiling water are at 100 degrees Celsius, steam causes more severe burns than boiling water does. This is due to the fact that steam contains more heat, in the form of latent heat, than boiling water does.
Is water an effective solvent to use?
Water is a very effective solvent since it can dissolve a wide number of various substances. This property makes water very useful. In addition, water is known as the “universal solvent” due to the fact that it is capable of dissolving a wider variety of chemicals than any other liquid. This makes it possible for the water molecule to become attracted to many different kinds of molecules other than water.
Does the pressure have an effect on the latent heat of vaporization?
As the pressure rises, the pressure’s effect on the molecules helps to bind them together, so the removal of a smaller amount of heat would likewise perform the trick. Hence, the latent heat of vapourization similarly increases with increasing pressure at a temperature of 100 degrees, whereas the latent heat of condensation decreases with increasing pressure.
What does it indicate when it says that the latent heat of vaporization is high?
In a similar vein, the high latent heat of vaporization (see below) suggests that latent heat is released into the environment when water vapor (obtained from evaporation of water at the ocean’s surface driven by solar energy receipt at low latitudes) condenses into liquid droplets at high elevations or high latitudes. This occurs when the water vapor is subjected to conditions that cause it to do so at high elevations or high latitudes.
What are the two different kinds of heat that are latent?
Latent heat of vaporization and latent heat of fusion are two prominent types of latent heat. Fusion (melting) is a form of latent heat. When a substance changes from one phase to the next, such as from solid to liquid or liquid to gas, these labels define the direction in which energy is transferred.
How can you determine the latent heat that steam possesses?
8 The evaporation factor of the liquid. H equals the amount of total heat contained in one kilogram of steam at a working pressure higher than zero degrees Celsius, measured in kilojoules per kilogram. T = Heat in feedwater (kJ/kg). The latent heat of steam at standard atmospheric circumstances is equal to 2256.
What are the three different kinds of heat that are latent?
- Latent Heat of Fusion,
- Latent Heat of Vaporization,
- Latent Heat of Sublimation.
At a temperature of 100 degrees Celsius, can liquid and steam coexist?
This type of heat is referred to as the Heat of Vaporization. The temperature does not rise at any point during the transformation process. So, it is not impossible for there to be both liquid water and steam present when the temperature is 100 degrees Celsius.
Does an increase in temperature make liquid expand?
When heated, each of the three forms of matter—solid, liquid, and gas—expands to a greater volume…. The same thing causes liquids to expand, but because the bonds between individual molecules in liquids are often less tightly bound, liquids expand more than solids do. Thermometers that include liquid in glass work according to this basic concept.
