Q. When water is heated from $ 0{}^\circ C $ to $ 10{}^\circ C $ , its volume:
EAMCETEAMCET 1999
Solution:
Unlike other liquids water contracts instead of expanding, when heated from $ {{0}^{o}} $ to $ 4{{\,}^{o}}C. $ after which it continues to expand in usual manner.
Water has least volume and maximum density at $ 4{{\,}^{o}}C. $ Therefore, due to anomalous expansion of water its volume decreases upto $ 4{{\,}^{o}}C $ and then increases.
