What are the particles of evaporation?
In evaporation, matter changes from a liquid to a gas. In condensation, matter changes from a gas to a liquid. All matter is made of tiny moving particles called molecules. Evaporation and condensation happen when these molecules gain or lose energy.
What happens to the particles when a liquid evaporates?
Evaporation happens when a liquid substance becomes a gas. When water is heated, it evaporates. The molecules move and vibrate so quickly that they escape into the atmosphere as molecules of water vapor.
What comes first gas or evaporation?
Evaporation happens when a liquid turns into a gas. It can be easily visualized when rain puddles “disappear” on a hot day or when wet clothes dry in the sun. In these examples, the liquid water is not actually vanishing—it is evaporating into a gas, called water vapor.
Where must the molecules of a liquid be in order to evaporate?
For molecules of a liquid to evaporate, they must be located near the surface, they have to be moving in the proper direction, and have sufficient kinetic energy to overcome liquid-phase intermolecular forces.
How will you describe the particles in liquid the particles in liquid are?
In liquids, particles are quite close together and move with random motion throughout the container. Particles move rapidly in all directions but collide with each other more frequently than in gases due to shorter distances between particles.
What is the change from liquid to gas?
A. Boiling and Evaporation: Evaporation is the change of a substance from a liquid to a gas. Boiling is the change of a liquid to a vapor, or gas, throughout the liquid.
When a liquid evaporates some molecules escape from it and its temperature changes?
Evaporation occurs when molecules escape from a liquid surface into the air above it. During this process the temperature of the liquid falls. Why does the temperature of the liquid fall? The molecules in the vapour expand because the pressure is less.
What is evaporation water cycle?
1 . Water evaporation is a physical process by which water changes from a liquid to a gas or vapour. This process takes place on the water surface starting at a certain temperature and until the air is saturated with vapour.
What is vaporization at the surface of a liquid?
Vaporization is the process of converting a liquid into a gas. It is also called evaporation.
What happens to molecules in a liquid?
In liquids, particles are quite close together and move with random motion throughout the container. Particles move rapidly in all directions but collide with each other more frequently than in gases due to shorter distances between particles.
What are the particles of a liquid?
Solids, liquids, and gases are made of tiny particles called atoms and molecules. In a solid, the particles are very attracted to each other. They are close together and vibrate in position but don't move past one another. In a liquid, the particles are attracted to each other but not as much as they are in a solid.
How will you describe the particles in liquid the particles in gas are?
Particles in a: gas are well separated with no regular arrangement. liquid are close together with no regular arrangement. solid are tightly packed, usually in a regular pattern.
What is the process of changing from a liquid to a solid?
The process by which a substance changes from the liquid phase to the solid phase is known as freezing.
What happens to the particles of a liquid when energy is removed from them?
When liquids boil the particles must have sufficient energy to break away from the liquid and to diffuse through the surrounding air particles. As these particles cool down and lose energy they will condense and turn back to liquid.
Why do only some of the particles break away from the surface of the liquid?
As a liquid evaporates, why do only some of the particles break away from the surface of the liquid? Why does the liquid evaporate faster if the temperature is increased? Only those molecules with a certain minimum kinetic energy can escape from the surface of a liquid.
What do you call the molecules that escape from the liquid and go into the gaseous phase?
The liquid molecules escape into the gas phase, becoming water vapor. Vaporization is the process in which a liquid is converted to a gas. Evaporation is the conversion of a liquid to its vapor below the boiling temperature of the liquid.
What are the steps of evaporation?
The water cycle consists of three major processes: evaporation, condensation, and precipitation. Evaporation is the process of a liquid's surface changing to a gas. In the water cycle, liquid water (in the ocean, lakes, or rivers) evaporates and becomes water vapor.
What are the 7 stages of the water cycle in order?
- THE WATER CYCLE.
- EVAPORATION.
- CONDENSATION.
- PRECIPITATION.
- INTERCEPTION.
- INFILTRATION.
- PERCOLATION.
- TRANSPIRATION.
What is required for surface particles of a liquid to break away to form gas?
If a liquid is heated the particles are given more energy and move faster and faster expanding the liquid. The most energetic particles at the surface escape from the surface of the liquid as a vapour as it gets warmer. Liquids evaporate faster as they heat up and more particles have enough energy to break away.
How do particles move in a liquid?
In liquids, particles are quite close together and move with random motion throughout the container. Particles move rapidly in all directions but collide with each other more frequently than in gases due to shorter distances between particles.
Why do liquids have the ability to evaporate?
Evaporation. Because the particles of a liquid are in constant motion, they will collide with one another, and with the sides of the container. Such collisions transfer energy from one particle to another.
What are particles of liquid?
Solids, liquids, and gases are made of tiny particles called atoms and molecules. In a solid, the particles are very attracted to each other. They are close together and vibrate in position but don't move past one another. In a liquid, the particles are attracted to each other but not as much as they are in a solid.
What is the phase change from liquid to gas called?
vaporization, conversion of a substance from the liquid or solid phase into the gaseous (vapour) phase. If conditions allow the formation of vapour bubbles within a liquid, the vaporization process is called boiling.
What happens to the particles when a liquid turns into a solid?
When a liquid turns into a solid the molecules slow down and begin to vibrate in place. To cause freezing energy must be removed. Because you are removing heat to freeze a substance it is called a exothermic change. The point at which this happens is called the freezing point.
What happens in vaporization and evaporation?
During vaporization, all of the water can turn into gas. As for evaporation, only the top level of water is turned into gas. When vaporization occurs, molecules could come from below the surface when the liquid is boiling. During evaporation, the molecules vaporize only from the surface of the liquid.

Solids, liquids, and gases are made of tiny particles called atoms and molecules. In a solid, the particles are very attracted to each other. They are close together and vibrate in position but don't move past one another. In a liquid, the particles are attracted to each other but not as much as they are in a solid.
What do you call the molecules that escape from the liquid?
The liquid molecules escape into the gas phase, becoming water vapor. Vaporization is the process in which a liquid is converted to a gas. Evaporation is the conversion of a liquid to its vapor below the boiling temperature of the liquid.
What is evaporation process?
Evaporation happens when the liquid turns into a gas. The process begins when the molecules of the liquid get energy in the form of heat. They then turn into a vapour after this gaining of energy.
What comes first in the water cycle?
The first step of the water cycle is evaporation. About 85% of the water vapor in the air comes from water that evaporated from the oceans. The other 15% comes from evapotranspiration, which is a catch-all term for water that evaporates from over land.
