What happens to the particles of a substance when it condenses gas — liquid?
As a gas cools, its particles slow down. When particles move slowly enough for their attractions to bring them together, droplets of liquid form. This process, which is the opposite of vaporization, is called condensation. As a gas condenses to a liquid, it releases the thermal energy it absorbed to become a gas.
What happens when you condense energy?
The latent heat of condensation is defined as the heat released when one mole of the substance condenses. The temperature does not change during this process, so heat released goes directly into changing the state of the substance.
What happens to particles when they are heated?
When particles are heated up, space is being created. The atoms started to get "overly excited" and started to move faster than they usually do. When this happens, energy is released in the form of heat, light or etc. Because of this, kinetic energy increases and atoms colliding with each other happens more often.
What happens to water vapour when it condenses?
Condensation is the process where water vapor becomes liquid. It is the reverse of evaporation, where liquid water becomes a vapor. Condensation happens one of two ways: Either the air is cooled to its dew point or it becomes so saturated with water vapor that it cannot hold any more water.
What happens to particles when they are cooled?
If it is cooled the motion of the particles decreases as they lose energy.
What happens when water condenses?
Condensation is the change of water from its gaseous form (water vapor) into liquid water. Condensation generally occurs in the atmosphere when warm air rises, cools and looses its capacity to hold water vapor. As a result, excess water vapor condenses to form cloud droplets.
Is energy released during condensation?
Latent heat of condensation is energy released when water vapor condenses to form liquid droplets. An identical amount of calories (about 600 cal/g) is released in this process as was needed in the evaporation process.
What happens to particles when heated and cooled?
When an object is heated the motion of the particles increases as the particles become more energetic. If it is cooled the motion of the particles decreases as they lose energy.
What happens to the particles of water when it is cooled?
What's happening in there? When water is cooled, the water molecules move slower and get closer together. This makes cold water more dense than room temperature water. Since cold water is more dense, it sinks in the room temperature water.
What causes condensation?
Condensation happens when your home is too humid and the warm air hits cold surfaces. This leads to the air cooling quickly and forming droplets on nearby surfaces such as walls/windows.
What is condensation for kids?
Condensation is a process by which a substance changes from a gaseous state to a liquid state. As a gas cools, it loses heat, or thermal energy. The particles that make up the gas move more slowly; that allows the attractive forces among them to increase, causing droplets of liquid to form.
What happens to particles when the temperature decreases?
As the temperature of a solid, liquid or gas increases, the particles move more rapidly. As the temperature falls, the particles slow down. If a liquid is cooled sufficiently, it forms a solid.
What happens to the particles of water during condensation and 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 of water when heated?
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. Evaporation is a very important part of the water cycle.
Why does condensation create heat?
Condensation: A Warming Process While condensation does cool the air inside of the air parcel, in order for that cooling to occur, that parcel must release heat into the surrounding environment. Thus, when speaking about the effect of condensation on the overall atmosphere, it warms it.
What happens to the particles of water when it is heated and then cooled?
When an object is heated the motion of the particles increases as the particles become more energetic. If it is cooled the motion of the particles decreases as they lose energy.
What happens to the particles of water when they are heated and then cooled?
A decrease in temperature caused the water molecules to lose energy and slow down, which results in water molecules that are closer together and a decrease in water volume. When water is heated, it expands, or increases in volume. When water increases in volume, it becomes less dense.
What happens when water vapor condenses?
Condensation is the change of water from its gaseous form (water vapor) into liquid water. Condensation generally occurs in the atmosphere when warm air rises, cools and looses its capacity to hold water vapor. As a result, excess water vapor condenses to form cloud droplets.
What must happen for condensation to occur?
Two things must be present for condensation to occur: warm moist air, and cool surface temperatures below the dew point. The proper control of these two factors can minimize condensation.
How do you explain condensation?
Condensation Definition Condensation is a change in the state of water from a gas or vapor form into liquid form. It generally happens when vapor in warm air encounters a cool surface.

Which conditions will make a substance condense?
A substance condenses when the pressure exerted by its vapour exceeds the vapour pressure of the liquid or solid phase of the substance at the temperature of the surface where condensation occurs.
What happens to the particles of water during condensation?
Water molecules in the vapor form are arranged more randomly than in liquid water. As condensation occurs and liquid water forms from the vapor, the water molecules become more organized and heat is released into the atmosphere as a result.
What happened to the particles of water when it is cooled?
What's happening in there? When water is cooled, the water molecules move slower and get closer together. This makes cold water more dense than room temperature water. Since cold water is more dense, it sinks in the room temperature water.
What happens during condensation in chemistry?
Condensation is the slowing down of a gas's molecules as they join together to create a liquid. When gas molecules transfer their energy to something colder, they slow down and become attracted to one another, forming a liquid. The rate of condensation is increased when water vapour is made colder.
What phase changes occurs during condensation?
During condensation, a substance is changed from the gaseous to the liquid state of matter.
What happens to particles when they are cooled or heated?
When an object is heated the motion of the particles increases as the particles become more energetic. If it is cooled the motion of the particles decreases as they lose energy.
What happened to the materials when cooled?
Heating a substance makes the molecules move faster. Cooling a substance makes the molecules move slower.
When water condenses what does it form?
Condensation is the change of water from its gaseous form (water vapor) into liquid water. Condensation generally occurs in the atmosphere when warm air rises, cools and looses its capacity to hold water vapor. As a result, excess water vapor condenses to form cloud droplets.
What is meant by a condensation reaction?
condensation reaction, any of a class of reactions in which two molecules combine, usually in the presence of a catalyst, with elimination of water or some other simple molecule. The combination of two identical molecules is known as self-condensation.
