Question

Ice floats on water. for most other substances however, the solid sinks in the liquid. classify each of these statements as true for water, or true for most other substances.

Answer 1

Answer:

Ice floats on water.  True

For most other substances however, the solid sinks in the liquid. True

Explanation:

The amount of matter in a certain volume is known as density. Density also determines how close together molecules are in a substance. In general, molecules that form solids are close together, which means that they are more dense than liquids, and this causes them to sink.

Water is a little different. When water becomes a solid, it is called ice. And the molecules of ice are organized in a way that makes them less dense than water. This means that ice floats on water.

Answer 2

Ice floats on water is a true statement. For most other substances such as solid will sink in the liquid is also a true statement.

Further explanation:

Ice floats on water because:

1. The liquid is denser than the solid.
2. When pressure is applied on solid (ice), it will convert it into liquid.
3. The molecules of the liquid are quite far from each other as compared to solid due to which it has a higher density.
4. In the phase diagram, the coexistence line, which lies between the solid and liquid, has a negative slope.

For most of the substances such as solid will sink in the liquid because:

1. The molecules of the solid are tightly packed.
2. The solid has more density than liquid.
3. When high pressure is applied to the liquid, it will convert it into solid.
4. In the phase diagram, the coexistence line that lies between solid and liquid show a positive slope.
