The intermolecular bonds between water molecules are hydrogen bonds.
When hot water is used to dissolve a gumball, the heat increases the molecular motion, allowing the color molecules to break free from the gumball at a faster rate. This rapid movement facilitates the release of the color molecules into the water. In contrast, warm water has less energy, so it takes longer for the color molecules to detach from the gumball, resulting in a slower removal of color.
Evaporation of water takes place as a result of the energy from the sun heating the water, causing some of the water molecules to gain enough energy to break free from the surface and escape into the air as water vapor. This process is driven by the transfer of heat energy to the water molecules, causing them to move faster and eventually escape as vapor.
The fastest moving molecules are more likely to break away from the surface of liquid water to form water vapor. This process is called evaporation, and it occurs when molecules with higher kinetic energy overcome the intermolecular forces holding them in the liquid phase.
Fire is pure energy being released. And it takes energy to move molecules around. Where ice is concerned, the water molecule has been sapped of all energy which causes it to remain in place and stick to other water molecules.. When the energy from fire comes in contact with the water molecule, the molecule absorbs the energy which causes the molecules to break away from each other and move. When the molecules break away and move is what causes a solid like ice to become a liquid.
the soap contains amphipathic molecules which can interact with hydrophobic as well as hydrophillic solvents. the hydrophilic end will interact with the water molecules whereas hydrophobic ends will concentrate at a very small portion and as a result a micell formation takes place.

That takes energy. Normal diffusion means that the molecules move away from each other (in other words ... to where there are less molecules).

Soil erosion is primarily caused by the combined effects of wind and water, which wear away the topsoil.
In hot water the water molecules are moving at a faster rate than they move in cold water. The faster moving molecules hit the salt molecules with greater force and knock them away from the other salt molecules faster. That way the salt molecules dissolve in the water quicker.
When the heat is added to water, the atoms in the water particle get enough energy, they end up being so poweful, they are able to pull away from other atoms and bounce around. It's sort of like heating water, the water is getting boiled and the water turns to steam. When energy/heat is taken away from the gas form, the steam turns back into a water form. To make it simple, The molecules get energy from heat.
The process in which water molecules move away from each other to become water vapor is called evaporation. It occurs when heat energy is added to liquid water, causing the water molecules to gain enough kinetic energy to break free from the liquid and become a gas.
the water molecules move away, e.g. evaporate
it slowly dissolves by being broken up and pulled away by the water molecules.
