kinetic energy
they get their energy from heat
liquid
locked up in hexagon shaped framework, in three dimensions, small space between these six molecules, giving ice a slighly lower density than liquid water. water molecules are hydrogen bonded together
When liquid molecules absorb enough heat energy, evaporation occurs.
Molecules in a liquid must overcome intermolecular forces before they can evaporate. The molecules must also be moving in the right direction and located near the surface in order for evaporation to occur.
It gets warmer. So, the water molecules absorb some kinetic energy, and begin to try and overcome to intermolecular attraction between them. Eventually, at 100 deg. C., they are finally able to move apart, and this represents water's boiling point, the point at which the water molecules have enough kinetic energy to no longer be attracted to each other.
Technically, the molecules are close together and vibrate in place. They do not stay move fast enough to overcome the attraction between them.
Technically, the molecules are close together and vibrate in place. They do not stay move fast enough to overcome the attraction between them.
When water is hot enough, the motion of the individual water molecules is fast enough to overcome the attraction that water molecules have for each other, which results in their escape from the liquid into the gas phase.
the force of attraction between its molecules becomes strong enough to overcome the energy of motion that its molecules have when the substance is in its liquid state, molecules are locked into rigid crystalline formations.
liquid
It is, but the lif generated by its wings is strong enough to overcome that attraction.
liquid
doesnt take the shape of its container

When liquid molecules absorb enough heat energy, evaporation occurs.
More molecules have enough energy to overcome the attractive forces holding them in the liquid.
Hydrogen bonding is the attraction of H atoms in the water molecule (slight + charge) to O atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. But it is still strong enough to help the water molecules "stick" together.
