ICSE Class 9 Physics Anomalous expansion of 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.
Wood has a density less than water.
When pressure increases and temperature decreases, density becomes highest. Therefore, the density of the neon will be highest at a temperature of 0∘C(lowest temperature) and pressure of 2 atm (highest pressure).
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 causes
Aquatic Life experiences the anomalous expansion of water. Bottle burst and soft drinks bottle are other examples of the same.
Recall the concept of Anomalous expansion of water
Two water properties due to hydrogen bond are-Cohesion and Adhesion
When ice melts its volume will decrease
