Nothing happens to the water molecules themselves, except that they move faster. Boiling is a physical change, not a chemical one. All that happens is the weak attractive forces between different water molecules are broken and individual molecules are turned into a gas, which is steam.
Upon boiling, the energy fueled to the water has reached the summit of latent heat capacity of water and is enough to overcome the molecular forces or polarity attractions between the water molecules. As the water molecules about 7 to 8 natural clumping together is broken apart, the water molecules exist in gas form and free into the atmosphere from the water. If the water is just merely heated but not reaching boiling point, what happened to the water is evaporation. Evaporation occurs on the surface of the water which contacts with the air. As the temperature of the water increases, the water molecules are vibrating vigorously, but not high enough to change into gas form and are suppressed by the pressure of the water above them layerly. However, the superficial water molecules have the least water pressure acting on them, hence they can flee into the air. This is evaporation.
Boiling dirt will not change its composition. The water will evaporate, leaving behind the same dirt particles that were there initially.
Yes, water vapor particles in the gas above a boiling pan move faster than the water particles in the liquid. When water boils, the heat energy increases the kinetic energy of the water molecules, allowing some to escape into the air as gas. While the liquid water molecules are still moving, the vapor particles have higher energy and thus move more quickly.
As a block of ice begins to boil, the motion of the particles increases due to the input of heat energy. Initially, the particles vibrate in place more vigorously, causing the ice to melt into water. As more heat is added, the particles gain enough energy to break free from the solid structure and turn into a gas (water vapor), leading to the boiling of the water.
Adding salt to water raises the boiling point of the water, so it will take longer to reach the boiling point. The dissolved salt particles disrupt the formation of steam bubbles that normally help the water boil vigorously.

vaporization
The presence of white particles in water after boiling could be caused by minerals such as calcium or magnesium that have precipitated out of the water during the boiling process.
Boiling dirt will not change its composition. The water will evaporate, leaving behind the same dirt particles that were there initially.
After boiling, the film on water evaporates and disappears.
Yes, the particles in boiling water move further apart as the water heats up and expands. This leads to a decrease in density and an increase in volume of the water.
It melts
It stay the same
It simply Dies
Boiling the water increases its kinetic energy, causing the water molecules to move faster and collide with the salt particles more frequently. This disrupts the bonds holding the salt particles together, allowing them to dissolve into the water.
As the water heats up the pot you're boiling it in, the particles of the water receive more energy. The more energy the particles have, the faster they move and the farther they spread apart. When the water finally reaches 212 degrees Fahrenheit (100 degrees Celsius), its particles spread so far out that they make the transition from a liquid to a gas. Thus, making steam.
Yes
The boiling water cools and the freezing water warms up until they are both at the same temperature.
