It gets colder and either condenses to a liquid or freezes to a solid. Either way, molecular motion is slowed down slightly.

A substance loses energy during what two processes?
A substance loses energy both when it freezes and when it heats up.
What does a substance do when it is cooled?
It loses energy.
What is Freezing water exothermic or endothermic?
Freezing is exothermic as a substance loses heat to its surroundings when it freezes.
What happens to the distance between particles of a substance as it changes from a liquid to a gas?
The distance increases, as the particles become more energetic and the substance loses its definite volume, as the particles bounce around, due to heat/increased energy.
What is the difference between condensation and boiling?
Boiling : the temperature increases substance changes its form from liquid to gas atoms of the substance moves with the high kinetic energy by absorbing heat Condensing : the temperature decreases substance changes its form from gas to liquid atoms of the substance loses atomic kinetic energy by losing heat
A substance loses energy during what two processes?
A substance loses energy both when it freezes and when it heats up.
What does a substance do when it is cooled?
It loses energy.
What does a substance gain or lose when its temperature changes?
The density of the substance becomes higher because of the particles slow down and move closer together when the substance cools.
When a substance cools it loses?
thermal energy
When a substances cools it loses what energy to its surrounding?
When a substance cools, it loses thermal energy to its surrounding environment.
Earth loses heat energy to outer space mainly by?
Earth loses heat energy to outer space mainly by radiation.
What is Freezing water exothermic or endothermic?
Freezing is exothermic as a substance loses heat to its surroundings when it freezes.
When a substance loses energy to its surrounding environment?
exothermic
When a substance cools it loses what to its surroundings?
Thermal energy
What happen to the heat energy as a substance solifies?
what happen to the heat energy as a substance solidifies
What do you have to do to heat energy to freeze a substance?
You need to take heat energy out of the substance.
Does melting lose or gain temperaturre?
loses When ice melts it gains heat. The environment, however, loses heat. So what does heat have to do with temperature? Often they vary in the same direction; temperature has been likened to the average kinetic energy of the substance. Melting typically ( e,g,, for ice-water) clamps the temperature at a constant value, but heat flows into the substance that melts.
