Compare and contrast the movement of water molecules when water is in a solid liquid or gaseous state.

In gaseous form their movement is much faster as compared to liquid and solid state.

Explanation:

The water molecules move very fast when they have high kinetic energy and their K.E is increases by heating.

Water as solid:

In solid form consider the ice, water molecules can not move because they are packet tightly.

Any substance in solid form can not move because of compactness of structure.

Water as liquid:

In liquid form water molecules can flow and move because molecules are not tightly held like in solid form. But their movement not much faster like in case of gaseous state.

Water as gas:

When water is heated at high temperature molecules are converted into gaseous form. Their movement is much faster as compared to liquid and solid  state.

c is the answer because when something is left after something evaporates that shows the chemical change.
