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.
How does a substance change when it condenses?
Condensation: the substance changes from a gas to a liquid. Vaporization: the substance changes from a liquid to a gas. Sublimation: the substance changes directly from a solid to a gas without going through the liquid phase.
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 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 kind of change is condensation?
Melting, evaporation and condensation are examples of physical change, or change of state, and are distinct from changes that cause new materials to form through a chemical reaction.
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.
Why does condensation happen?
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. But condensation doesn't need a solid surface to take place, as it can occur when a warm pocket of water vapor encounters colder gasses.
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 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 substance is removed during 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.
What molecule is produced by a condensation reaction?
What happens in a condensation reaction? In a condensation reaction, covalent bonds form between monomers, and as these bonds form, water is released. This all results in the formation of polymers.
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.
How do you explain condensation to a child?

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.
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.
What is condensation process?
Condensation is the process of water vapor turning back into liquid water, with the best example being those big, fluffy clouds floating over your head. And when the water droplets in clouds combine, they become heavy enough to form raindrops to rain down onto your head.
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 when a substance 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.
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 is the product of condensation?
Products of condensation reactions include ethers, acetals, esters, imines, and amides. We now consider condensation reactions that yield polymers. Two functional groups are required in a monomer so that after one functional group reacts, the other is available to link to another monomer.
What is the end product of condensation?
A condensation reaction occurs when two molecules join to form a larger molecule and release a smaller molecule(s) in the process. The smaller molecule lost in the reaction is often water, but it can also be methanol, hydrogen chloride, acetic acid or several other molecules.
What happens during condensation in the water cycle?
Condensation is the process of a gas changing to a liquid. In the water cycle, water vapor in the atmosphere condenses and becomes liquid. Condensation can happen high in the atmosphere or at ground level. Clouds form as water vapor condenses, or becomes more concentrated (dense).
What is condensation short answer?
Condensation is the process where water vapor becomes liquid. It is the reverse of evaporation, where liquid water becomes a vapor.
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.
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.
