A block of wood is floating in water at 0 ∘ C . The temperature of only the water is slowly raised from 0 ∘ C to 1 0 ∘ C . With the rise in temperature of the water, the volume of the block above water level will:

From 0 to 4 ∘ C water density rises and less wood is submerged. Above 4 ∘ C density falls and more wood is submerged. The volume above water first increases, then decreases.

A block of wood is floating in water at $0^{\circ} C$ . The temperature of only the water is slowly raised from $0^{\circ} C$ to $1 0^{\circ} C$ . With the rise in temperature of the water, the volume of the block above water level will:

Options:

Answer:

Solution:

From $0$ to $4^{\circ} C$ water density rises and less wood is submerged.
Above $4^{\circ} C$ density falls and more wood is submerged.
The volume above water first increases, then decreases.
