What happens to water molecules when they are heated?
Like all molecules, a molecule of H20 is in constant motion; 'hot' molecules move faster than 'cold' molecules. If the molecules move slowly enough the substance appears stationary to us (frozen water) and if they move quickly enough they will expand to fill their container (vapor or gas water.)
What happens to molecules when water is turning into gas?
During the phase change from water to gas (vaporization), the intermolecular forces between water molecules are overcome, causing the molecules to break free and spread out more. This results in the water molecules becoming less dense and transitioning from a liquid state to a gaseous state.
When water molecules heat up and turn to steam the molecules begin to move?
When water molecules heat up and turn to steam, they gain energy and move more quickly, breaking the intermolecular bonds that hold them together as a liquid. This transition from liquid to gas is known as vaporization.
Do water particles in gas coming off of a pan of boiling water move slower that the particles of the water in the pan?
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.
How does the potential energy of water molecules changes as water changes from a solid to a liquid and then from a liquid to a gas?
As water changes from a solid (ice) to a liquid, the potential energy of the water molecules increases because the molecules move apart and have more freedom of movement, overcoming the rigid structure of the solid. When water transitions from a liquid to a gas (steam), the potential energy increases further as the molecules gain enough energy to break free from intermolecular attractions, allowing them to move independently in the gas phase. Thus, the potential energy of water molecules rises during both phase transitions.
What state of matter in which water molecules move the fastest?
In the gas state, water molecules move the fastest due to the higher kinetic energy they possess compared to the liquid or solid states. In the gas phase, water molecules are further apart and have more freedom to move around, resulting in higher speeds.
How does the movement of water molecules change when goes from liquid to gas?
The molecules begin to release and move into the air more quickly than they condense back into liquid.
What are some molecules that move by diffusion and osmosis?
Molecules that move by diffusion include oxygen, carbon dioxide, and water. During osmosis, water molecules move across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration.
What happens to water molecules when they are heated?
Like all molecules, a molecule of H20 is in constant motion; 'hot' molecules move faster than 'cold' molecules. If the molecules move slowly enough the substance appears stationary to us (frozen water) and if they move quickly enough they will expand to fill their container (vapor or gas water.)
Why gas have maximum freedom to move?
Because the attraction between gas molecules is negligible so its easy for gas molecules to move free
What happens to molecules when water is turning into gas?

Where did most water come from?
Most water, believe it or not, came out of thin air. Hydrogen molecules (a gas) bonded with oxygen molecules (another gas) when a certain kind of electric charge was present, which formed water. Thus, water formed out of thin air.
When water molecules heat up and turn to steam the molecules begin to move?
When water molecules heat up and turn to steam, they gain energy and move more quickly, breaking the intermolecular bonds that hold them together as a liquid. This transition from liquid to gas is known as vaporization.
What is happening to the molecules of water as they are heated?
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.
Which phase has the most energy?
The phase with the most energy is the gas phase. Gas molecules have higher kinetic energy compared to solid or liquid molecules because they have more freedom to move and collide with each other at higher speeds.
When a substance absorbs heat its molecules move faster and it?
And farther apart, and it changes phase: ice to water, water to gas,
What are the states of water How does it describe the arrangement of water molecule?
The three states of water are solid (ice), liquid (water), and gas (water vapor). In the solid state, water molecules are closely packed together in a specific arrangement, forming a crystal lattice structure. In the liquid state, water molecules are more loosely arranged and able to move past each other. In the gas state, water molecules are far apart and move freely.
