When Water(Liquid State) is cooled,the energy of molecules of water is absorbed by freezer and their movement is slowed down and they form a structure ICE(Solid State).
Though density of ICE should have been greater than water since molecules are coming close due to loss of energy,But it is not the case,Water shows anomalous behavior below 4C where the density starts to decrease with temp and hence ice floats on Water.
Exploding of potassium metal when placed in water
It was dissolved
Water kept in freezer looses heat and turns into solid as soon it reaches below its melting point.
The freezer takes heat out of the air in it, and discards the heat elsewhere. As long as the air in the freezer is colder than the water in the ice-cube tray, heat flows out of the water into the air around it, and is removed by the freezer. If the temperature of that air happens to be lower than the melting/freezing point of water, then the water eventually freezes at some time during the process.
The hot atmosphere
.o_O. lol
you freeze the substance in a FREEZER
Put it in the freezer
Well, the weight of the freezer will change when something is put in, but the freezing of these materials will NOT change their weight.
A chemical change occurred

A freezer is a appliance that maintains a low enough temperature to freeze whatever is placed inside it, often food. Ice is frozen water, often made in a freezer.
Liquid water placed in a freezer will become solid ice.
This is an experiment. it will change from liquid to solid.
It freezes
xxcxcxc
It is a physical change. When the water vapour inside of the freezer turns to frost (ice), it hasnt changed the fact that it is still water, just in a different form. Therefore, this is a physical change.
