Unlike most substances, when water freezes, it forms a structure that is less dense than the liquid it is in equilibrium with (which is why ice floats on liquid water). It is also unusual in that the maximum density of the liquid reaches a minimum at a temperature ABOVE the freezing point - roughly 1.0000 g/cm3 at 4 °C - before it begins to increase as it approaches the freezing point. Water thus has a negative coefficient of thermal expansion between 0 °C and 4 °C and a zero coefficient right at 4 °C. Other substances have uniformly positive coefficients of thermal expansion.

What is the increase of the volume of a substance by the increase of temperature called?
This increase of volume is called expansion
What is happening to a substance undergoing thermal expansion?
the water separate everywhere
Water expands as it freezes can you define a coefficient of volume expansion for the freezing force?
The coefficient of the thermal expansion of water is equal to .00021. Water expands by 9% of its volume when it freezes.
What is thermal expansion and explain its two types?
- Thermal expansion is the dimension modification of a material under heating. - Linear, volumetric and area thermal expansion are known and measured for materials.
What are the two types of thermal expansion?
Linear, volumetric and area thermal expansion are known and measured for materials.
What is the increase of the volume of a substance by the increase of temperature called?
This increase of volume is called expansion
What are the of objectives of thermal expansion in solids and liquids in everyday life?
one example of thermal expansion is when in the kitchen and you can not open a can of vegetable(example) you will put it in a pan of hot water and the water will push it off.

How does thermal expansion affect a bridge?
A bridge must have expansion gaps or else they will waver when they expand in warm temperatures. This is thermal expansion
Liquids expansion by heat?
Yes as friend Des Dichado pointed out liquids do have thermal expansion.
What does thermal expansion of water mean and why is it relevant to the rising sea levels?
Thermal expansion relates to how things expand when they heat up and contract when they cool down. This also applies to the water in the ocean. The hotter it is, the more it expands, making sea levels rise.
What are the disadvantages of the anomalous expansion of water?
water has the property of expanding when cooled at a temperature below 4`C. As a result water pipes burst due to the anomalous (strange) expansion of water in the colder regions.
The expansion of matter when it is heated is known as?
thermal expansion
What is the thermal expansion coefficient for steel c 15?
thermal expansion depends on Temperature and material of steel
