As the heat is removed, the kinetic energy of the particles decreases and they start moving very slowly. Quick reminder: kinetic energy is the energy associated with a particle's motion. The faster a particle moves, the larger its kinetic energy is.
When enough energy has been removed from the system and the particles are in super slow motion, bonds begin to form between the molecules. These bonds act like glue and freeze the molecules into place.

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.
What happens when the body heat causes its molecules to vibrate and move farther away?
you sweat
When heat is taken away from matter it loses energy and its temperature decreases?
yes
What is the pressure of helium?
The pressure that there would be if all the non-helium atoms and molecules were taken away.
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 when energy is taken away?
What happens when thermal energy is taken away
What happens is energy is taken away from matter?
When thermal energy is taken away from matter particles move more slowly. When thermal energy is added to matter particles move faster.
When a body is taken away against gravitational force what happens to its potential energy?
It increases.

What must be added or taken away in order for matter to changes states?
Energy must be added or taken away.
What happens to water vapor when energy is taken away?
If enough energy is taken away from water vapour, it will condense to form water (in liquid form). This is because a gaseous state requires more energy than a liquid state (and a liquid state requires more energy than a solid state).
What happens to particles when heat energy is absorbed during melting?
After heat energy is absorbed during melting the atoms and molecules start moving away from each other as the force of attraction becomes weak. At one point the atoms or molecules move so further away that the solid turns into a liquid.
When water evaporates what happens to the molecules?
When the heat is added to water, the atoms in the water particle get enough energy, they end up being so poweful, they are able to pull away from other atoms and bounce around. It's sort of like heating water, the water is getting boiled and the water turns to steam. When energy/heat is taken away from the gas form, the steam turns back into a water form. To make it simple, The molecules get energy from heat.
What happens to energy as it travels away from the sources?
Energy is lost
What has to be taken away to turn water into ice?
energy
What is convection heating from a campfire?
The simplest answer is: the fire adds heat energy to the air molecules near it. The higher energy molecules start bouncing around faster. When these molecules move away from the fire, they carry the energy (heat) with them.
What happens to water when heat is taken away?
It becomes cold.
