ICSE Class 9 Physics Anomalous expansion of water
|
Recall the causes
Dew point is an example of anomalous expansion of water.
Two water properties due to hydrogen bond are-Cohesion and Adhesion
Aquatic Life experiences the anomalous expansion of water. Bottle burst and soft drinks bottle are other examples of the same.
The seawater applies more buoyant force than normal water. Its density is more than normal water. Seawater contains mineral salts that increase the density of it.
Specific heat is the amount of energy required to change the temperature of the substance. This high specific heat of water enables the moderation of climate on Earth and organisms can regulate their body temperature.
Recall the definition
Wood has a density less than water.
Expansion of water when it is cooled from four degrees Celsius to zero degrees Celsius is observed. The density of water decreases instead of increasing as the temperature falls from 4 degrees to 0 degrees.
Recall the concept of Anomalous expansion of water
