What happens to the molecules in a glass of water as the water evaporates?
The energy of a molecule is made up of potential and kinetic. so as kinetic increases, potential decreases. Also as when molecule is in gaseous state, the distance between molecules is much greater than that in a liquid, so the potential energy is less as a gas NOTE a molecule has potential energy when it is a certain distance away from its equilibrium position between adjacent particles during its vibrations in a liquid. Kinetic energy is motion energy. SO in there is less attraction between adjacent molecules, so potential energy is less.
What happens to the energy put into a liquid during boiling?
The energy put into a liquid during boiling is used to break the intermolecular forces between the liquid molecules, allowing them to escape as vapor. This energy is then stored as latent heat in the vapor molecules.
What best explains what happens when liquid water evaporates to form water vapor?
When water molecules at the surface gain sufficient energy they can escape in the atmosphere.The energy of water molecules increase by a temperature increase and some molecules at the surface can escape in the atmosphere.
How do you change liquid to gas?
To change the phase of a system from liquid to gas, the total system energy must be increased (heat added) to the point where every atom or molecule has sufficient energy to escape the liquid system.
What happenes when liquid is exposed to air?
When liquid is exposed to air, it tends to evaporate. This happens because the molecules are in constant motion, and from time to time, a molecule achieves sufficient energy to overcome the atmospheric pressure above the liquid, and it escapes as a vapor.
What happens if a molecule with a high kinetic energy happenes to be close to the liquid's surface?
Then that molecule will escape the surface of the liquid and become a molecule of gas. This is the process by which water slowly evaporates even when not heated.
How water changes to a gas?
Like all other liquid to gas transitions, liquid water changes to gas: by absorbing energy from its surroundings or by having energy added to it. The molecules in a mass of water will have a distribution of energies, as will the gas above the surface. When a molecule at the surface collides with another molecule of sufficient energy, it can absorb energy from the collision and potentially acquire enough energy to escape from the liquid. If energy is being added to the liquid - as heat or agitation - there are more molecules with sufficient energy to make this happen. Energy can also be added directly to the liquid at the surface in the form radiant energy - such as the sun shining on it. A molecule can absorb this energy directly and thus gain enough energy to escape the surface of the liquid.
What happens to molecules with sufficient energy when a liquid is placed in a closed container?
When a liquid is placed in a closed container, molecules with sufficient energy can escape from the liquid and turn into gas. This process is called evaporation.
How does a gas become a liquid?
By cooling. With less thermal energy, the kinetic energy of each molecule becomes less. Therefore some of the gas molecules can no longer escape the attraction of like molecules. As they join together we perceive them as liquid.
What happens when high energy particles leave the surface of the liquid?
When high energy particles leave the surface of a liquid, it causes the liquid to evaporate. Evaporation occurs when molecules at the surface gain enough energy to escape into the air as gas.
What happens to substance during changes between gas to liquid?
The particles of the substance gain kinetic energy as they absorb heat energy. Eventually there is enough kinetic energy for the particles to escape the liquid phase, forming the gas phase.
What happens to substance during changed between liquid and gas?
The particles of the substance gain kinetic energy as they absorb heat energy. Eventually there is enough kinetic energy for the particles to escape the liquid phase, forming the gas phase.
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.

The energy put into a liquid during boiling is used to break the intermolecular forces between the liquid molecules, allowing them to escape as vapor. This energy is then stored as latent heat in the vapor molecules.
What happens to a liquid when releases enough energy?
When a liquid releases enough energy, it can undergo phase change into a gas through the process of evaporation or boiling. The energy supplied helps break the intermolecular forces holding the liquid molecules together, allowing them to escape into the gas phase.
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.
