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 else can I help you with?
What are the properties and characteristics of salt water?
It raises the boiling point and the freezing point of water than normal.
What happens to the properties of each substances when water is mixed with salt?
When water is mixed with salt, the properties of the salt remain unchanged. However, the properties of the water may change, such as its boiling and freezing points. The salt dissolves in the water, forming a homogeneous solution.
How does salinity change the properties of water?
Salinity increases the density of water, making it heavier. It also affects the boiling and freezing points of water, raising the boiling point and lowering the freezing point. Additionally, increased salinity can make water less hospitable for many aquatic organisms.
Does pure water have colligative properties?
Yes, pure water does have colligative properties. Colligative properties depend on the number of solute particles in a solution, not the specific identity of the solute. Pure water exhibits colligative properties such as boiling point elevation and freezing point depression.
Does the amount of water change the boiling or freezing point of water?
No, the amount of water does not change the boiling or freezing point of water. The boiling point of water is always 100°C (212°F) at sea level, and the freezing point is always 0°C (32°F). The boiling and freezing points are determined by the chemical properties of water, not the amount of water present.
What kind of property is melting point and freezing point of water?
The melting point and freezing point of water are physical properties. The melting point is the temperature at which ice (solid) changes to water (liquid), while the freezing point is the temperature at which water (liquid) changes to ice (solid).
How does freezing water affect the physical properties of the substance?
Freezing water causes it to expand and form a solid structure, changing its physical properties. The solid ice is less dense than liquid water, which is why ice floats. Additionally, freezing water can affect its transparency and ability to dissolve other substances.
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?

When water is mixed with salt, the properties of the salt remain unchanged. However, the properties of the water may change, such as its boiling and freezing points. The salt dissolves in the water, forming a homogeneous solution.
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
What is the impact of temperature on the physical properties of water above freezing temperature?
The impact of temperature on the physical properties of water above freezing temperature includes changes in density, viscosity, and thermal conductivity. As temperature increases, water becomes less dense, more viscous, and better at conducting heat.
How does flash freezing water affect its properties and characteristics?
Flash freezing water can lead to the formation of smaller ice crystals, which results in a smoother texture and potentially clearer appearance compared to slow freezing. This process can also help preserve the natural flavor and nutrients of the water.
How does salinity change the properties of water?
Salinity increases the density of water, making it heavier. It also affects the boiling and freezing points of water, raising the boiling point and lowering the freezing point. Additionally, increased salinity can make water less hospitable for many aquatic organisms.

What do you do if you are in freezing water?
Get out of the freezing water.
