When more molecules join a liquid than leave, the process is known as condensation. This occurs when vapor molecules in the air transition into the liquid phase, typically due to a decrease in temperature or an increase in pressure. As a result, the amount of liquid increases, leading to a higher density of liquid in that area. This phenomenon is commonly observed in processes like dew formation or the condensation of water vapor in the atmosphere.
What else can I help you with?
What happens to the molecules when there is a change in state from liquid to solid?
When a liquid changes to the solid state, the molecules slow down so that they only vibrate in place and can no longer flow like a liquid.
Where does evaporation take place in a liquid?
Evaporation takes place at the surface of a liquid. (There is an article about evaporation on Wikipedia that may be helpful if you have any more questions about evaporation.) ~KKMG1
What happens to movement and position of molecules when they change from a liquid to a solid?
When molecules change from a liquid to a solid, they lose energy and begin to move more slowly. As the temperature decreases, the molecules arrange themselves into a more ordered and fixed structure, resulting in a solid state. This transition reduces the freedom of movement significantly, causing the molecules to vibrate in place rather than move freely as they do in a liquid.
Does condensation take place when particles leave a liquid and become a gas?
No, condensation occurs when gas particles lose energy and transition into a liquid state. The process involves the gas particles coming together due to cooling, which results in the formation of liquid droplets.
Is energy released or required for evaporation to take place?
Energy is required for evaporation to take place. This energy, in the form of heat, is needed to break the bonds between liquid molecules so they can escape into the air as gas.
What is the difference between the molecules in a hot solid and hot liquid?
The molecules in a solid vibrate in place. The molecules of a liquid are moving about.
What is the state of matter where molecules are in the same place but aren't joined?
A liquid has adjacent molecules that are not locked into place.
Why do liquids cool as evaporation takes place?
As a liquid evaporates, molecules with higher kinetic energy leave the liquid surface, which results in a decrease in the average kinetic energy of the remaining molecules and, therefore, a decrease in temperature. This cooling effect is due to the energy required to break the intermolecular bonds holding the liquid molecules together during evaporation.
What happens to the molecules when there is a change in state from liquid to solid?
When a liquid changes to the solid state, the molecules slow down so that they only vibrate in place and can no longer flow like a liquid.
How does the mass of the evaporating dish and its content change as heating take place?
As heating takes place, the mass of the evaporating dish and its contents will decrease due to the evaporation of the liquid content. The liquid will turn into gas and escape into the surroundings, resulting in a decrease in mass as the water molecules leave the dish.
What occurs when molecules are distributed evenly through a solid liquid or a gas?
When molecules are evenly distributed through a solid, liquid, or gas, we say that the substance is in equilibrium. In a solid, the molecules are tightly packed and vibrate in place. In a liquid or gas, the molecules move freely and randomly.
What is different about the h2o molecules when the 100 milliliter of water is changed from a liquid to solid?
The molecules are unchanged. They are however fixed in one place and unable to move around freely as they did in the liquid.
Differences between gas liquid and solids?
gas-energetic molecules that randomly move, free from meach other liquid- cohesive force stronger than gas, can move, but cannot separate from the rest of the molecules solid- molecules held firmly in place, particles can only vibrate in place
Where does evaporation take place in a liquid?
Evaporation takes place at the surface of a liquid. (There is an article about evaporation on Wikipedia that may be helpful if you have any more questions about evaporation.) ~KKMG1
What is different at the molecular level between a solid and a liquid?
At the molecular level, the main difference between a solid and a liquid is the arrangement and movement of molecules. In a solid, molecules are tightly packed together in a fixed position, vibrating in place. In a liquid, molecules are more loosely packed and can move around each other, allowing the liquid to flow.
Are molecules of a substance in motion only as a gas?
No, they are in motion in a liquid as well. In a solid they vibrate in place.
Why is evaporation called surface phenomenon?
evaporation is called a surface phenomenon because the particles of liquid gain energy from the surroundings , having higher kinetic energy, is able to break the away from the forces of attraction of other particle . that is why it is called a surface phenomenon
