Question

Why does ice float after it crystallizes? Its mass is greater than water. Its density is greater than water. Its density is less than water. Air trapped in ice causes it to float.

Answer 1

Its density is less than water

Answer 2

Ice floats after it crystallizes because ITS DENSITY IS LESS THAN THAT OF WATER.

When a quantity of water is cools down by reducing its temperature, the molecules of the water lose kinetic energy and slow down in their movement. As the water is cooling down, it is volume is expanding. When the temperature reaches zero degree Celsius, the water becomes ice. At this point, the ice can float on water because its density is less than that of water; this is as a result of the spaces that now exist in the ice structure.
