//**2)Condensation is the process of gas changing into liquid. The particles lose heat energy when cooled, as a result, Kinetic energy of particles decreases. Attractive forces or intermolecular forces between particles get stronger and draw them together. Then gas changes into liquid. Therefore, the particles get closer to each other like the liquid's properties.**//=====

//**3) Melting is the process of turning a solid into a liquid. It is when a solid [such as ice] gains heat energy the particles inside the solid become excited and move further apart. The solid then becomes a liquid. **//=====

//**3) Freezing is the process of turning a liquid into solid. It is when a liquid(e.g. Water) loses heat .**// //**4)****When water freezes, the molecules are locked into place in a crystal structure, and it turns into a hard solid, or ice. The ice is hard because unlike in water, where the individual H2O molecules are free to move about and are not fixed in position, in ice each of the molecules is connected to the molecules next to it, making it hard. Freezing is a change of state of a material or substance, and it is a physical (not a chemical) change.**// //**5)Water expands when being frozen.**//
