Water’s density increases as it freezes or at lower temperature.
<h3>How cold water has more density?</h3>
Cool water has more density because cooling a substance leads to molecules to slow down and get closer to one another, occupying a smaller volume that results in an increase in density while on the other hand, the warm water is less denser and will float on room-temperature water.
So we can conclude that cold water is more dense and will sink in room-temperature water.
