As water is heated, the water molecules gain kinetic energy and they move faster. Eventually, they get enough kinetic energy to move fast enough to escape the liquid phase and become a gas/vapor. This is the boiling point.
the molecules evapourate
The liquid molecules are transformed in gas molecules.
Water atoms do not expand or multiply when heated. When water is heated, the heat energy causes the water molecules to move faster and farther apart, which results in the expansion of the water volume. The number of water molecules remains the same.
up because when heated, it becomes light and goes up.
The liquid molecules are transformed in gas molecules.
yes they do
As water is heated, its density decreases. When water molecules are heated, they gain energy and move around more, causing the molecules to spread out and the water to expand. This expansion leads to a decrease in density.

When water is heated from 25 C to 155 C, it undergoes a phase change from liquid to gas at its boiling point of 100 C. The water molecules gain energy, move faster, and eventually overcome the intermolecular forces holding them together as a liquid, transforming into steam.
up because when heated, it becomes light and goes up.
When water molecules are heated, they gain energy and start moving faster. This increased movement causes the water molecules to break the hydrogen bonds holding them together, transitioning from a liquid to a gaseous state known as water vapor.
At higher temperature the continuous movement of water molecules is accelerated.
