Question # 1

Explain anomalous expansion of water

Ans 1: Water on cooling below 4 C begins to expand until it reaches 0 C On further cooling its volume increases suddenly as it changes into ice at 0 C When ice is cooled below 0 C it contract i.e its volume decreases like solids. This unusual expansion of water is called anomalous expansion of water
