Detailed explanation-1: -Detailed Solution. The correct answer is It shall first decrease and then increase.
Detailed explanation-2: -first decreases and then increases.
Detailed explanation-3: -Density of water is maximum at 4oC. So during heating from 0oC to 10oC, its density increases at first and then it decreases resulting in the decrease in volume at first and then increase in its volume.
Detailed explanation-4: -When water is heated, it expands, or increases in volume. When water increases in volume, it becomes less dense. As water cools, it contracts and decreases in volume.
Detailed explanation-5: -When water is heated from 0oC to 4oC it contracts continuously instead of expanding. That means its volume decreases upto 4oC.
