Melting point:Melting point is the temperature at which a solid becomes a liquid at normal atmospheric pressure.

Boiling point: Temperature at which the vapor pressure of the liquid equals the pressure surrounding the liquid and liquid change to vapor (and vice versa).

Evaporation:Evaporation is the process of a substance in a liquid state changing to a gaseous state due to an increase in temperature and/or pressure.

Matter can exist in one of three main states: solid, liquid, or gas. Solid matter is composed of tightly packed particles. A solid will retain its shape; the particles are not free to move around. Liquid matter is made of more loosely packed particles.

Insulator. Any material that keeps energy such as electricity, heat, or cold from easily transferring through is an insulator. Wood, plastic, rubber, and glass are good insulators.

Ans2:Three States of Matter

Matter can exist in one of three main states: solid, liquid, or gas.Solid matter is composed of tightly packed particles. ...Liquid matter is made of more loosely packed particles. ...Gaseous matter is composed of particles packed so loosely that it has neither a defined shape nor a defined volume.

Ans3:condensation. Boiling - liquid to gas Boiling point Boiling point of pure and impure substances. Evaporation Condensation - gas to liquid. Boiling, evaporation andcondensation are terms that refer to the changes in state between liquids and gases:Boiling occurs when a liquid is heated and turns to a gas.

1.Ans.Plastic, wood and glass are good electrical insulators. Thermal insulators are used to prevent the flow of heat. These are used to keep our homes warm inside when there are cooler temperatures outside.

Heat insulation means preventing the heat ( Thermal energy) losses from the system. By using insulation material. I am giving you a example in Power plants, the super heated steam is used drive the turbine in order to produce the power.
