Well, when energy is added to a liquid, the liquid moves faster, thus it gets warmer and can turn to gas. So you figure out what the opposite would be, and voila! you have your answer.

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 do you notice about its temperature during boiling?
When a liquid is boiling the temperature stays constant. This is because the heat energy you are adding is being taken away with the vapour being produced.
What is the complete subject of the sentence - To change a liquid to a solid heat must be taken away?
heat
When heat is taken away from matter it loses energy and its temperature decreases?
yes
When heat is taken away from water it changes from a liquid to what?
Water changes to a solid, ice, when heat is taken away from it. You can think of putting water into the freezer. Since the freezer is cold, heat flows out of the water making it become ice cubes.
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 must be added or taken away in order for matter to changes states?
Energy must be added or taken away.
Is solid the state of matter which is made when heat is taken away from a liquid?
Yes
What happens when energy is taken away?
What happens when thermal energy is taken away
How does he amount of energy change during boiling?
During boiling the temperatre of the boiling liquid does not go up. The energy input into the boiling liquid is taken away as the latent heat of evaporation by the escaping gaseous phase.
Is heat taken away or added in evaporation?
Taken away. As a liquid evaporates, it loses heat to the atmosphere.
How is it possible for liquid water to turn into a gas at temperatures below its boiling point?
"Temperature" measures average thermal energy - but it's statistical. Outlier atoms will have sufficient energy to break away from the liquid state.
Can the state of matter change when you add or take away energy?
Yes, particularly if you add thermal energy. At its least energetic, matter is in the solid state. Add some more energy, it transitions to the liquid state. Then more and it's a gas. Finally, at its most energetic, it is in the plasma state.
What happens to energy in a substance when i change state?
As energy is absorbed, the energy moves up to other electron shell levels, but as the energy is released, it goes back to zero (ground state) and the energy is given off as light.
Why does the temperature of a substace remain constant even though energy is being added?
As a liquid is heated that energy is translated into kinetic energy of the molecules. At boiling point the kinetic energy of the hottest molecules is sufficient to drive them off into the gaseous state. As more energy is added, more molecules are driven off. This carries large amounts of energy away, leaving the temperature of the liquid unchanged. The temperature will not rise until all liquid has entered the gaseous state.
Why does it take so much energy to change a liquid to a solid?
You actually take away energy to turn a liquid into a solid.
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.
