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.
When ice starts to melt what happens to the temperature until it completely changes to all water?
During a change of state (phase) there is only a change in the potential energy of the molecules, not the kinetic energy. The energy is used by the molecules to rearrange themselves into positions they have in the liquid state.
When a substance changes from a liquid to a gas energy is . When a substance changes from a gas to a liquid energy is .?
When a substance changes from a liquid to a gas energy is absorbed. When a substance changes from a gas to a liquid energy is released.
Why evaporation is a cooling process?
according to kinetic theory,the temperature is a measure of average kinetic energy of the molecules of a liquid.during evaporation,the escape of high energy molecules from the surface of a liquid,lowers the average kinetic energy of the remaining molecules and therefore,the temperature of the liquids falls down.thus evaporation is a cooling process.
Do water molecules in the liquid state have more energy than water molecules in the polar state?
Do water molecules in the liquid state have more energy than water molecules in the polar state
Does potential increase or decrease when gas changes to liquid?
The potential energy of a substance decreases when it changes into a liquid. This is because it's losing the heat energy it had when in gas form to become liquid.

Do molecules gain or lose energy from melting?
When matter melts (changes from a solid to a liquid state), its molecules move faster, meaning they are gaining energy.
When solid and liquid phases are in equilibrium which phase solid or liquid contain the greater amount of energy?
The answer depends on the specifics of the question. The idea though, is that when they are in equilibrium, both the solid and the liquid should have the same amount of energy PER MOLECULE. The fact that there is a solid component and a liquid component means that either the solid is melting or the liquid is freezing. In most situations, that means that the temperature of the whole mixture is constant. Another idea is that the energy in the molecules can either be kinetic or potential energy. Basically, the more kinetic energy PER MOLECULE an object has, the higher the object's temperature. Furthermore, the more potential energy PER MOLECULE that the object has, the further apart the molecules are from each other. Combining these ideas, here are a few possible answers to your question. 1. There is more solid than liquid. On average, the solid's molecules have the same kinetic energy as the liquid. The solid, having more molecules, has more kinetic energy total. The liquid has more potential energy in total. The solid has more overall energy. 2. There is more liquid than solid. On average, the liquid's molecules have the same kinetic energy as the solid. The liquid, having more molecules, has more kinetic energy total. The liquid also has more potential energy in total. The liquid has more overall energy. 3. There are equal amounts of liquid and solid. On average, the liquid's molecules have the same kinetic energy as the solid. The liquid has equal kinetic energy as the solid due to the even split. The liquid also has more potential energy in total. The liquid has more overall energy. These three are the main possibilities, and as can be seen in the details, the answer depends on the relative amounts of liquid and solid.
Describe how a solid changes into a liquid and how a liquid changes into gas?
both can be achieved by applying heat and breaking up the formation of the molecules at different levels of applied energy.

What happens when liquid solids or gas absorb heat?
the molecules gain or lose energy, the more energy these molecules have the easy it is for them to break the bonds holding them together, thus when you apply enough heat to a substance it changes from a solid to a liquid then from a liquid to a gas.

Why solids will have less energy then the same materials in liquid or gas state?
To convert a material from solid to a liquid, the atoms or molecules - which are held together by chemical bonds - must be broken apart. That is, potential energy must be provided to the atoms or molecules. Similarly, when changing from a liquid to a gas, additional energy needs to be provided.
When Matter changes state from a liquid to a gas why do the molecules move faster?
Cause when you add energy it gets stimulated.
