Evaporation and Condensation

Evaporation is an endothermic process that is the conversion of a liquid to the vapor state by the addition of latent heat. Condensation is a type of chemical reaction in which water or another simple substance is released by the combination of two or more molecules. The term is also used to describe the process by which a gas or vapor changes to a liquid. In weather, evaporation occurs when water on the earth changes to water vapor and enters the atmosphere. The opposite of evaporation, condensation transforms water vapor in the atmosphere into a liquid, often resulting in precipitation, most commonly in the form of rain or snow.

Why does water not evaporate when it is kept in pre heated pan?

User Avatar

Asked by Wiki User

Water in a preheated pan may not evaporate immediately because the water needs to reach its boiling point before it evaporates. Once the pan reaches a high enough temperature to boil the water, the water will start to evaporate into steam.

When water is evaporated?

User Avatar

Asked by Wiki User

Water evaporates when it is heated or exposed to sunlight, causing its molecules to gain enough energy to break free from the liquid phase and enter the air as water vapor. This process is essential in the water cycle as it leads to cloud formation and precipitation.

When water is evaporated heat is what?

User Avatar

Asked by Wiki User

When water is evaporated, heat is absorbed from the surroundings in order to break the bonds between water molecules. This absorbed heat causes the water molecules to gain enough energy to change from a liquid to a gaseous state.

Is concrete a compound after the water evaporates and it hardens?

User Avatar

Asked by Wiki User

Concrete is not a compound after water evaporates and it hardens. Concrete is a mixture of aggregate materials (such as sand and gravel) and cement, which binds the materials together. When water is added to the mixture, a chemical reaction occurs with the cement that causes it to harden and bind the aggregate materials together.

Which of the elements are used in make a synthetic rain?

User Avatar

Asked by KumarPerumal

Elements used in making synthetic rain typically include silver iodide, potassium iodide, and sodium chloride. These substances are used to artificially induce precipitation by seeding clouds to encourage the formation of rain droplets.

What happens after liquid water evaporates and turns into steam?

User Avatar

Asked by Wiki User

When liquid water evaporates and turns into steam, the water molecules gain enough energy to overcome the forces holding them together, becoming a gas. Steam is then released into the air as water vapor, which can condense back into liquid water when it cools down.

Which liquid is having the highest rate of evaporation?

User Avatar

Asked by Wiki User

The liquid with the highest rate of evaporation would generally be the one with the lowest boiling point. This means that substances like acetone or ethanol, which have low boiling points, will evaporate more quickly than water or oil.

What would you do if you were in space with limited oxygen?

User Avatar

Asked by Wiki User

If I were in space with limited oxygen, I would try to conserve my oxygen supply by breathing slowly and deeply. I would also try to find a way to replenish my oxygen, such as locating an oxygen tank or making my way back to the spacecraft for more supply. Staying calm and rationing my oxygen usage would be crucial in such a situation.

Which cycle involves the movement of water by the processes of evaporation condensation transpiration and precipitation?

User Avatar

Asked by Wiki User

The water cycle, also known as the hydrological cycle, involves the continuous movement of water on, above, and below the surface of the Earth through the processes of evaporation, condensation, transpiration, and precipitation. Water evaporates from bodies of water, transpires from plants, condenses in the atmosphere to form clouds, and returns to the Earth as precipitation.

Will water evaporate from a container?

User Avatar

Asked by Wiki User

Yes, water can evaporate from a container if the temperature is high enough for the liquid to reach its boiling point. Evaporation is the process in which water molecules escape from the surface of the liquid and enter the air as vapor.

Can you water plants with the water from an evaporative dryer?

User Avatar

Asked by Wiki User

No, it is not recommended to water plants with water from an evaporative dryer. The water from an evaporative dryer often contains salts and other minerals that can be harmful to plant health. It is better to use clean, fresh water for watering plants.

Does cordial evaporate quicker than water?

User Avatar

Asked by Wiki User

No, cordial does not evaporate quicker than water. Both cordial and water evaporate at a similar rate since they both contain water as the primary solvent. Factors such as temperature, surface area, and humidity levels will influence the rate of evaporation for both substances.

How fast does water in a above ground pool evaporate at 80 degrees in a week?

User Avatar

Asked by Wiki User

The rate of evaporation of water from an above ground pool at 80 degrees Fahrenheit can vary based on factors such as humidity, wind speed, and pool size. On average, you can expect around 1/4 to 1/2 inch of water to evaporate from the pool in a week at that temperature. It's recommended to monitor the water level regularly and adjust as needed.

How does condensation and evaporation affect your climate?

User Avatar

Asked by Wiki User

Condensation releases heat to the atmosphere, warming the climate. Evaporation cools the area by absorbing heat from the environment. Both processes contribute to the water cycle, which helps regulate temperature and humidity in a region, influencing climate patterns.

Is evaporation when liquid water turns into water vapor?

User Avatar

Asked by Wiki User

Not immediately. First it turns into steam, the gaseous form of water. Depending on where the water is, it may eventually be attracted to dust in the air to form clouds, which may eventually become rain.

Which of the following evaporate in the water cycle?

User Avatar

Asked by Wiki User

Water from oceans, lakes, rivers, and streams evaporate as part of the water cycle.

How do you do condensation problems?

User Avatar

Asked by Acotton358

Condensation problems typically occur when warm, moist air comes into contact with a cooler surface, causing the moisture in the air to condense into water droplets. To prevent condensation, you can increase ventilation to reduce humidity levels, use dehumidifiers, insulate surfaces to avoid temperature differences, or use moisture-absorbing materials like silica gel.

What evaporates quicker fresh water or tap water?

User Avatar

Asked by Wiki User

Tap water typically evaporates quicker than fresh water due to the chemicals and minerals added during the treatment process. These additional components can increase the rate of evaporation compared to fresh water which does not contain these extra substances.

How does increased air movement effect evaporation?

User Avatar

Asked by Wiki User

Increased air movement can speed up evaporation by carrying away the water vapor that is being released from the surface of a liquid. This helps to maintain a lower concentration of water vapor in the air around the liquid, creating a gradient that encourages more water molecules to evaporate.

What remains when water is evaporated after a neutralization reaction?

User Avatar

Asked by Wiki User

After water is evaporated from a neutralization reaction, any remaining substances would be the salt that was formed as a result of the reaction between an acid and a base. Salt is the compound left behind after the water has been removed.
