An aluminium sphere is dipped into water. Which of the following is true?

View answer and explanation

Correct option: A

Buoyancy will be less in water at

0^{\circ} \mathrm{C}

than that in water at

4^{\circ} \mathrm{C}

.

Option A (Buoyancy will be less in water at

0^{\circ} \mathrm{C}

than that in water at

4^{\circ} \mathrm{C}

) is correct because water has its maximum density at

4^{\circ} \mathrm{C}

, resulting in greater buoyancy.
