What is common between melting and evaporation?
they either take away heat or heat is added.
How does evaporation change from a liquid to a solid?
It doesn't. Evaporation is the change of state from a liquid to a gas, caused by added surface heat. You're thinking of freezing, caused by loss of heat.
What is necessary for evaporation to occur?
Heat, or energy, is needed for evaporation to occur. Energy breaks bonds holding water molecules together, making evaporation possible.
What happens to some liquids like melted butter when heat is taken away?
they resolidify
Are necessary for evaporation to occur?
For evaporation to occur you need the following: Heat (energy), and water.
What is common between melting and evaporation?
they either take away heat or heat is added.
Is heat energy being added or removed during the process of evaporation?
In condensation heat is removed In evaporation heat is added
Is heat taken away or added in sublimation?
Sublimation is an endothermic physical change (heat is needed).
Heat being added or taken away from a substance may cause?
more or less heat
What occurs when liquids change to gases as heat is added?
evaporation
Is sweating a chemical reaction?
Oddly enough, evaporation is endothermic. To tell the difference, simply ask yourself, must heat be added or taken away for a phase change to occur. If heat must be added it is endothermic, if heat must be taken away it is exothermic. In the case of evaporation in most cases you must raise the temperature for a substance to evaporate, thus it is endothermic.
What must be added or taken away for a change in the state of matter to occur?
I believe "heat"To change from one state of matter to another state of matter heat is added or taken away.I think that makes sense!
Evaporation is a cooling process because?
heat is radiated away
How does evaporation cool down a fire?
evaporation takes away heat from the fire thereby reducing it's energy.
How does evaporation change from a liquid to a solid?
It doesn't. Evaporation is the change of state from a liquid to a gas, caused by added surface heat. You're thinking of freezing, caused by loss of heat.
Is heat released to the environment or taken up from the environment during evaporation?
Heat comes from one source, the sun.
Is heat absorbed or released during evaporation?
Heat is absorbed by the molecules leaving the place the evaporation is occuring. That is why, after putting aftershave or cologne, you feel cold. The alcohol in the aftershave/cologne has evaporated and taken the heat from your face with it.
