This is a change of phase from liquid to solid.
Water freezing in bottle when opened happens in the case of supercooled water. This water has been cooled below freezing point without being crystallized.
The boiling water cools and the freezing water warms up until they are both at the same temperature.
it drops
it rises
the temperature increases
The freezing point of the water is lowered. ADD: You get a salt water solution.
Contaminated water also freeze, but the temperature of freezing can be lower.
The vibration of the atoms slows and they condense together.
the water will rise and will bob about before settling then melting/freezing depending on the temperature
Yes, salt does lower the freezing point water. This happens because some of the water is displaced by the salt thus decreasing the number of molecules able to be easily frozen.
Melting occur faster then freezing
It is from the liquid phase to the solid phase. It is called freezing.
