A substance that carries electricity under certain circumstances but not under others is called a semiconductor.
Just make a physics model of the properties which are associated with electricity but are tangible in the real world. I.e. the water analogy of electricity. Water pressure is voltage, electrical current is analogous to water flow rate and a restriction in a water pipe could be resistance. but it is important that this is only a model for certain circumstances and will break down if you try to carry the analogy too far.
A substance change from a solid to a liquid at its boiling point. This is when it reaches a certain temperature.
It is the price your utility company charges you for the power it supplies to you.
It means that some substance is capable of being dissolved in liquid - possibly only in certain liquids.

This material is an electrical conductor.
semiconductors! SEMICONDUCTORS it will do it in some condition
Objects that conduct electricity poorly are called poor conductors of electricity or insulators . There is a difference though. Poor conductors of electricity are capable of conduction under certain circumstances while insulators cannot conduct electricity under any condition, example ; air is a poor conductor of electricity as it cannot conduct under normal conditions but lightning is able to pass through it during a storm.
A substance that fits that description is a gas, such as hydrogen or oxygen. Gases have no definite shape or volume and can conduct electricity under certain conditions.
No. An atom consists of protons, neutrons and electrons.Electrons can, in certain circumstances, be moved or shared with other atoms. This is the basis of chemistry and electricity.
semiconductors: other materials which conduct only under certain conditions
No, the pressure is the force exerted by the substance on the walls of its container. The word that comes to mind for "amount of substance in a certain volume" is concentration, though it might also be a somewhat awkward way of describing density.The amount of substance in a certain volume is the density of the substance. Pressure means the force applied in a unit area. So the amount of substance in a certain volume is not the pressure.
Each of those has energy; so each of them MAY, under certain circumstances, knock an electron out of its orbit around the atom, or make it move around.
