Statement 1: The level of water (initially at $0^{\circ} C$ ) in a vessel which does not expand on heating begins to decrease on putting it on a gas stove.
Statement 2: The density of water initially increases when its temperature rises from $0^{\circ} C$ .

Question

Statement 1: The level of water (initially at $0^{\circ} C$ ) in a vessel which does not expand on heating begins to decrease on putting it on a gas stove.

Statement 2: The density of water initially increases when its temperature rises from $0^{\circ} C$ .
