During evaporation, intermolecular interactions are broken so that molecules leave the liquid phase (where they are more closely packed and interact more frequently) and enter the gas phase (where they are essentially so far apart that they no longer interact with each other, an assumption of the Kinetic Molecular Theory). The substance does not change identity and no covalent bonds are broken or formed.

What makes evaporation and condensation alike?

Evaporation and Condensation are based upon the energy in the water molecules. If the water temperature (vapor) is above the surface temperature, it will evaporate. If the water temperature (vapor) is below the surface temperature it will condense. Evaporation and condensation are happening at the same time. We add the term "Net" at the beginning to show which is happening at a greater rate. The temperature at which there is net condensation is referred to as dew point.


What happens to the water during the process of evaporation?

During evaporation, water changes from a liquid state to a gas state. This occurs when the water molecules gain enough energy to break free from the liquid and become vapor in the air.


What doese evaporation mean?

Evaporation is the process by which a liquid, such as water, changes into a gas, usually due to heating or exposure to sunlight. During evaporation, molecules near the liquid's surface gain enough energy to escape into the air as vapor.


What happens to water during evaporation and how does this process occur?

During evaporation, water changes from a liquid to a gas by absorbing heat energy from its surroundings. This process occurs when water molecules gain enough energy to break free from the liquid and become vapor in the air.


Evaporation is what kind of process?

Evaporation is a physical process by which a liquid substance transforms into a gaseous state at a temperature below its boiling point. During evaporation, individual molecules gain enough kinetic energy to escape the liquid surface and enter the gas phase.

What is the chemical change in evaporation?

There isn't one. Evaporation is a physical change.


During a temperature change what is happening to the substance?

A change of phase: melting, evaporation, liquefaction or chemical changes as thermal dehydration, thermal decomposition, oxydation, etc.


What is lost during the process of evaporation?

During the process of evaporation, liquid water is converted into water vapor, which is a gas. This means that the water loses its liquid state but its molecular composition remains unchanged. No molecules are lost during evaporation, only the physical state of the water changes.


Is evaporation physics or chemistry?

Evaporation is a physical process where a liquid turns into a gas. While the behavior of molecules during evaporation follows physical principles, understanding the specific interactions between molecules and the energy changes involved can also involve chemical concepts. Therefore, evaporation can be considered a combination of physics and chemistry.

Which process represents a chemical change...Melting of ice OR Evaporation of water?

The process that represents a chemical change is the evaporation of water. This is because the bonds between the H and O atoms in water molecules are broken during evaporation, leading to a change in the substance's chemical composition. The melting of ice, on the other hand, is a physical change where the state of water changes from solid to liquid without altering its chemical structure.


Is baking a cake physical or chemical changes?

Baking a cake involves both physical and chemical changes. The physical changes include mixing the ingredients, changing the shape and texture of the batter, and the evaporation of water during baking. The chemical changes occur when the heat causes the baking powder to react, creating bubbles that make the cake rise, and when proteins and starches denature and coagulate during baking.


Is mixing cement a chemical or physical change?

Actually both physical and chemical changes are happening during cement mixing.


Does gas always indicate a chemical change?

No, the presence of gas does not always indicate a chemical change. Gas can form due to physical processes such as evaporation or changes in temperature, without any chemical reactions taking place.


Does evaporation produce carbon dioxide?

No, evaporation is the process by which a liquid, such as water, changes into a gas, such as water vapor. During evaporation, carbon dioxide is not produced.
