Q. wo identical beakers are filled with water to the same level at $4^{\circ}C$. If one say A is heated while the other B is cooled, then :

Solution:

As at $4^{\circ} C$ temperature water density is maximum, on increasing or decreasing temperature density decreases so in both beakers the liquid level will rise.
