What makes a liquid freeze?
Answers:
Cold temperature.
The freezing point of water is 0°C (32°F, 273 K)

Removing the heat from it.
colder than 32 degrees F
the molecular structure changes to a solid
When a liquid cools down, it is actually losing it's heat and energy. The hotter a liquid is, the more energy its molecules have. So when you put a liquid in the freezer, the molecules lose a lot of energy and move a lot less and eventually stick to one an other solidly.
cold temperature
the cold temperature
Liquids become solids when their rapidly moving molecules slow down to a point that they are in stasis creating a solid (ice). The temperature at which this happens varies dependant on the amount and type of particulates in the water. Ex: fresh water freezes at 32F but ocean water freezes at 28F. So the more particles, the more energy in the water.
When the liquid called water gets to the temperature of 32 degrees F or 0 degrees C the molecules slow down to a point of stopping and create ice crystals which are frozen and sometimes called GLASS.
When that ice melts above 32 degrees and it becomes warmer those molecules start to move faster(water)--- in fact when they get too fast they fly off into the air as STEAM at 212 degrees F ( 100 degrees C)
All molecules, including water molecules (even those in a glassful of
still water) are constantly moving. Heat makes them move faster, cooling
slows them down. When water gets cool enough, molecular movement is slowed
enough that the molecules stick to each other and form ice crystals.
As water gets cold, the particles slow down. When the
particles slow down, they line up in a nice crystal pattern and the water
become solid.
Water particles (molecules) are a little "sticky":
they tend to hold together when they touch. At room temperature, the water
particles do not stick together for very long, because they are moving too
fast. When the temperature gets lower and the particles slow down, it is
easier for them to hold on to each other. Below 0 Celsius (32 Fahrenheit),
the water particles move slowly enough that they do not detach from each
other. So, they hold together in a solid block, which we call "ice".
