Which phase change occurs during evaporation?
The phase change that occurs during evaporation is when a liquid changes into a gas. This process happens when the molecules of the liquid gain enough energy to escape into the air.
What is a evaporation in science words?
Evaporation is the process by which a liquid, such as water, transforms into a gas or vapor, usually due to an increase in temperature. During evaporation, molecules at the surface of the liquid gain enough energy to overcome the forces of attraction holding them in the liquid state, allowing them to escape into the air as a gas.
What changes taken place during evaporation?
During evaporation, a liquid turns into a gas or vapor by gaining energy from its surroundings. The molecules of the liquid gain enough energy to overcome the attraction forces holding them together in the liquid state. As they gain energy, the molecules move more rapidly and eventually break free into the surrounding environment as a gas.
What is vapor and how does it relate to the process of evaporation?
Vapor is the gaseous form of a substance, such as water vapor. It relates to the process of evaporation because when a liquid evaporates, it turns into vapor. Evaporation occurs when molecules at the surface of a liquid gain enough energy to escape into the air as vapor.
What does liquid become during evaporation?
During evaporation, liquid becomes vapor or gas as it changes from a liquid state to a gaseous state. This process occurs when the liquid's temperature increases to the point where its molecules gain enough energy to escape into 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.
Why does evaporation require that heat energy be added to a substance?
Evaporation requires heat energy to be added because it provides the molecules in a substance with enough kinetic energy to overcome the attractive forces holding them together. As molecules gain energy, they move faster and escape the liquid phase, transitioning into the gas phase. This process leads to evaporation.
What causes the particles of a substance to evaporate?
Evaporation occurs when individual particles of a substance gain enough kinetic energy to break free from the attractive forces holding them in the liquid phase. As these particles escape into the air, they create a vapor above the liquid. The rate of evaporation is influenced by factors such as temperature, surface area, and the strength of intermolecular forces in the substance.
What 3 changes of state absorb thermal energy?
Melting, evaporation, and sublimation are changes of state that absorb thermal energy. During these processes, the particles in a substance gain energy to break intermolecular bonds and overcome attractive forces between them, resulting in an absorption of thermal energy.
Do molecules move slower or faster or the same during evaporation?
Molecules move faster during evaporation because when a liquid evaporates, the molecules gain energy from the surroundings, increasing their kinetic energy and causing them to move more rapidly.
Which phase change occurs during evaporation?
The phase change that occurs during evaporation is when a liquid changes into a gas. This process happens when the molecules of the liquid gain enough energy to escape into the air.

What happens to particles of a liquid during evaporation?
During evaporation, particles of a liquid gain enough energy to escape from the surface and become vapor or gas. As the liquid evaporates, the average kinetic energy of the remaining particles decreases, leading to cooling of the liquid and its surroundings.
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.
With the input of solar energy water changes from a liquid to a gas during the process of?
evaporation. This happens when sunlight heats up the water molecules, causing them to gain enough energy to escape into the air as water vapor.
