Question

What will happen to water level, will it rise in two beakers? Why?

Answer 1

Explanation:

The volume of the liquid gets greater as it is heated. The greater the rise in temperature the more it expands. ... This is because the glass gets hot first and so expands and the volume of the beaker therefore increases. This means that the water level will drop.

Answer 2

So when volume changes density changes. Since water contracts form 0°C to 4°C,its volume decreases and the density increases to reach the maximum value at 4°C. When water is cooled from 100°C it contracts till it reaches 4°C; then it expands. So in both beaker water must rise.
