When something goes from it's liquid form to solid, it is a heat loss. A simple example is making an ice-pop in a freezer. The liquid fruit-juice/water mixture has to lose heat to the freezer (and the other contents) in order to solidify. Subsequently it has to gain heat from your mouth to melt when you eat it (which is why it feels cold).

More simply, steam at 100 degrees C is "hotter" (contains more energy) than water at 100 degrees C.
Looking at it the other way around - from liquid to gas makes everything clear: When you boil water, you put in 1 calorie of heat energy and 1 ml of water goes up by 1 degree C. This goes on, with your test tube constantly having the temperature change for the better. Then we reach 100 degrees (water boiling point). Now we put in more heat, but the temperature stays put. Instead, the water turns to vapor.
Having said this, perhaps it would help to clarify what "gaining heat" is. There are two ways of looking at the question: Intuitively, the way we perceive it, and scientifically, which is probably what this question is about.
First: Intuitively - If the liquid "gained heat" - either it's temperature would be higher (as shown by a thermometer inserted in the liquid), or the surrounding temperature would go down (in order to give energy to the liquid, so now the surroundings lost some energy which the new liquid gained). But neither happen. Rather, JUST THE OPPOSITE happens:
The liquid "LOOSES HEAT" - but it's temperature does not go down. The surrounding temperature goes UP! In order to explain this intuitively, I like to think of a sponge. Liquid is the sponge all squished, while the gas is a free sponge, ready to absorb (heat).
When the sponge is squished, the heat leaves it.
Now to the scientific perception: In science you don't look at things as "pushing" or "causing". You look at the numbers before and after, and say: So and so is what "happened". So your not looking at the "squishing" but rather just checking things at the different stages. When it was gas: Its temperature was A, and the surroundings were B. Now the liquid's temperature is still the same, but the gas around it heated up.

Is evaporation heat gain or heat loss?
For what?It requires a heat gain for the water,but a heat loss for whatever the water is in contact with.
Why is a thermos flask good at keeping drinks cold as well as hot?
Because it has good insulation so it prevents boss loss and gain of heat from the surrounding ---- Well that's true, but more interestingly, it has a glass chamber inside which is smaller than the outer casing. The air between the glass chamber and the outer casing has had almost all of the air removed, and is therefore a vacuum. This makes the heat unable to escape between the inner chamber and the outer casing, keeping the liquid hot. It also stops heat from outside being able to get into the liquid stored in the glass chamber, therefore keeping it cold. Most of the heat from the flask is lost from the lid, since the liquid has to come out of somewhere.
What do all changes of state in matter require?
heat energy
Describe a method of insulation that can completely eliminate heat loss by conduction?
Installing fiberglass batting will completely eliminate heat loss.
The rate of heat loss from the hot cup change during the experiment answer?
The rate of heat loss from the hot cup decreased during the experiment.
By removing heat what happesn 1. a liquid changes to a solid. 2 a solid changes to a liquid. 3 a liquid changes to a gas. 4. a solid changes to gas?
1. a liquid changes to a solid. This process is called freezing, and involves the loss of heat.
What are the six phases of matter and their meaning?
freezing -to pass from the liquid to solid state by loss of heat
What is required for a phase change to occur?
Change of the phase of electrical current in a circuit or of an el magnetic wave propagating in space means change of the rate of oscillations per second of the source (generator, in particular) of the oscillations. In FM (frequency modulated )radio wave transmission sounds (music, speach) are made to modulate frequency of the generator - its rate of oscillations is changing according to the changes in phase of the vibrations of sound waves in air.
Is precipitation heat loss or heat gain?
heat loss
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.
Requires a gain or loss of heat energy?
A temperature change requires as gain or loss of heat energy.
Is melting heat gain or heat loss?
Heat gain, otherwise, a heat loss would be like turning off the heat beneath a saucepan on the stove.
What is the temperature at which a liquid changes to a solid called is there a gain or a loss of energy?
Such a temperature is known as Freezing point of the liquid, during the freezing process the system losses the energy.
Is evaporation heat gain or heat loss?
For what?It requires a heat gain for the water,but a heat loss for whatever the water is in contact with.
What is adiabatic combustion?
NO Heat Loss , No Heat gain
What is the difference between heat gain and heat loss?
These are exact opposities - heat gain is an increase in energy that results in an increased temperature of the material. Heat loss is a loss in energy that results in a decreased temperature of the material.
What makes a liquid a solid?
a loss in energy cause the change from liquid to solid like-wise a rise in energy causes a change from solid to liquid.
