Water (chemical formula: H2O) is a liquid between 0oC and 100oC in Earth's atmosphere. As it decreases in temperature, the net volume of a body of water will decrease, until the water reaches around 4oC.
At 4oC, water molecules begin to form a lattice. This lattice becomes stronger as the temperature of the water decreases (turning it into a solid, ice), causing a body of water to expand. This is an uncommon physical property, as most substances decrease in volume as their temperature decreases.
This property is demonstrated when a sealed container filled completely with water is cooled extremely quickly (placed in liquid nitrogen, for instance). As the water inside the container freezes extremely quickly, the container will explode, due to the rapid expansion of the water inside it.

What properties of water protects organisms from overheating and freezing easily?
specific heat
What are the properties and characteristics of salt water?
It raises the boiling point and the freezing point of water than normal.
What are the properties of coolants?
Coolant has these properties... it absorbs heat from the engine, which is why you put it in there it also has a lower freezing and higher boiling point than water it inhibits corrosion and lubricates the water pump
Is juice freezing a chemical change?
No, it is only a physical change since the chemical properties of alcohol do not change.
What is one chemical property of water and one physical property?
See this link.
What kind of property is melting point and freezing point of water?
The melting point and freezing point of water are physical properties.
What properties of water protects organisms from overheating and freezing easily?
specific heat
How does salt effect the properties of water?
Salt increases the boiling point of water and lowers its freezing point.
What are the properties and characteristics of salt water?
It raises the boiling point and the freezing point of water than normal.
Does plain water evaporate quicker than salt water?
Yes, this is based on the colligative properties of liquid. Whenever, a solute( like salt) is added to a solvent(like water), the following happen to the properties of the solvent. 1. Elevation of freezing point. 2. Depression in freezing point
The scale of temperature independent on thermal properties?
Only the Kelvin scale. The Celsius scale, for example is based on the thermal properties of water, as is the Reaumur scale. The Fahrenheit scale is based on the freezing point of brine, the freezing point of water and, possibly, the normal body temperature.
What are the properties of coolants?
Coolant has these properties... it absorbs heat from the engine, which is why you put it in there it also has a lower freezing and higher boiling point than water it inhibits corrosion and lubricates the water pump
What are the effects of impurities in boiling and freezing point?
AnswerImpurities tend to increase the boiling point and lower the freezing point.in a way boiling point of salty water > boiling point of fresh waterfreezing properties of salty water < freezing properties of fresh watermelting properties of salty water < melting properties of fresh water.Salt water, contains NaCl, which ionizes into Na and Cl ions. when ions are added to a solvent, such as water, they tend to increase the boiling point and lower the melting point.
Salininty how does it affect salt water?
The physical properties are different between pure water and salted water (density, freezing point, boiling point, conductivity etc.).
Is the water in you a chemical or physical property?
The water, itself, is not a property. It is a compound. Properties of water are things like boiling point, freezing point, density, color, etc.
Are boiling points and freezing points examples of chemical properties?
No, they are physical properties.
What do you do if you are in freezing water?
Get out of the freezing water.
