Because there are three positive charged conductors and there is electrical pressure in between.

What is this system called with three single phase transformer?
Your question is rather vague. If you are asking what do you call a group of single-phase transformers, connected to supply three phase, then the answer is a 'three-phase transformer bank'.
What is the difference between three phase load and phase supply?
How much current equipments are drawing from three phases (combined or individual) is called three phase load and how much supply we are getting from source is called three phase supply. Ex. In INDIA single phase supply is 220 volt ac with neutral. So in three phase supply all RYB phases should be 220 volts ac with neutral individually. If we calculate with phase to phase than it shoulb be 415 volts ac.
What is it called when the three states change?
changes of state are called phase changes.
What are the three types of phase on its final phase?
single phase, double phase & three phase
Two phase instruments?
There is no such thing as a two phase instrument. There is only single phase and three phase. You can only have: single phase/ one pole single phase/ two pole three phase/ three pole
Single phase and three phase circuit?
Yes, there is a difference between single phase and three phase circuits.
What is phase supply and three phase supply?
I think you mean 'single-phase supply', rather than 'phase supply'. All high-voltage a.c. transmission and distribution systems are three-phase systems. This is because, for a given load, a three-phase system uses less copper than a single-phase system. Three-phase generators produce three 'phase voltages', each displaced, by 120 electrical degrees. These voltages are produced in three windings which are electrically connected in what is called a 'delta' configuration, with each 'corner' of the delta connected to the transmission system by 'line' conductors. Three-phase systems are either 'three-wire' or 'four-wire' systems. Generally, three-phase, three-wire, systems are used for high-voltage transmission and distribution, whereas three-phase, four-wire, systems are typically (but not always) used for low-voltage distribution. Three-wire systems comprise three conductors called 'line conductors'; four-wire systems comprise three 'line conductors' and a 'neutral conductor'. Depending the voltage standards used in the country in which you live, a single-phase supply is obtained either by connecting single-phase load between any two line conductors, or between any one line conductor and the neutral conductor.
Is three phase is ac or dc?
Three phase is ac
What is the point where pressure and temperature are just right for all three phases to exist at once on the phase diagram called?
This point is call the "triple point" and this is where all three lines meet together on the phase diagram.
How do you start a three phase motor to a single phase power supply?
You don't. A three phase motor will not start unless it is connected to a three phase supply.
What is the first phase of glycolysis called?
The first phase of glycolysis is known as the preparatory (or investment) phase, because this phase consumes energy to convert the glucose into two three-carbon sugar phosphates (G3P).
Can 3 single phase transformers can replace 1 three phase transformer?
Yes, you can use three single phase transformers on three phase applications and interconnect them to serve as a single transformer or you could use one single phase transformer fed from two of the three lines in a step down application.
