Most plastics are actually liquids .... they are just very viscous. The glass in your window is also a liquid. A solid has a defined crystal structure. Things like asphalt, plastic, and glass don't have a crystal structure and are therefore liquids. Really think, viscous liquids. As you heat them, they become softer and softer as opposed to melting and changing to a liquid all at once.
A saline solution is formed.
A solid melts when it reaches its melting point, which is the temperature at which the intermolecular forces holding the solid's structure together weaken enough for the solid to turn into a liquid. Increasing the temperature provides the necessary energy for the particles to overcome these forces and transition into a liquid state.
No, freezing changes a liquid to a solid. To change a solid to a liquid you need to apply heat. The change begins when the solid reaches its melting point.
Heat makes most things expand. Or in other words, heat makes matters less dense.(With the very known and remarkable exception of water, ice which will decrease in size when it becomes water and becomes more dense until it reaches 4 degrees Celsius, from which point on it will expand again.)Heat can make matters change state.Ice (solid) into water (liquid), water (liquid) into steam (gas).
When heat is added to a solid, its particles start vibrating more rapidly, increasing their kinetic energy. This causes the solid to expand slightly as the particles spread out. If enough heat is added, the solid may reach its melting point and turn into a liquid.
When a liquid looses enough energy (heat), it turns into a solid.
A material in solid phase changes to its liquid phase by absorbing energy. The intermolecular(inter-particular) bonds are broken as the temperature increases until enough bonds are broken that the rigid shape of the solid can no longer be maintained.*The energy required to turn a solid into a liquid, of the same temperature, is called the latent heat of fusion.
The addition of thermal energy, or heat, if you prefer, will turn solid water (ice) into a liquid by melting it.
When a solid absorbs heat, it may melt and turn into a liquid. When a liquid absorbs heat, it may vaporize and turn into a gas. Conversely, when a gas releases heat, it may condense and turn into a liquid, and when a liquid releases heat, it may solidify and turn into a solid.
It is called sublimation when you turn a solid into a gas. When you turn a gas into a solid it is called deposition.
Theoretically, anything can be changed from a solid to a liquid with enough energy added. Consequently, any gas can be changed into a liquid when enough energy is removed from it.
It depends on the solid. Stone would probably become molten lava. Metals would become liquid and could by poured into moulds. Solid ice would turn into water.
Steam, possibly just hot water, but if enough is added(212 Degrees F)(100 degrees C) than it will turn into water vapor.
