PVC is cheaper but is used differently. PVC is usually baried in ground and emt usually runs exposed. You can use PVC exposed if it is schedule 80 gray PVC electrical conduit. Schedule 40 is for under ground
Conduit Bodies are usually grey or silver in color. They are made of metal, fiber, plastic or fixed clay. It is an electrical tubing used for protection and routing of electrical wiring.
What kind of wire? If it's a power wire, why is the place wired with conduit? Commercial buildings must put all power wiring in conduit, so if you're planning to run romex in a commercial building, the answer would be "no", it's not permissible. If it's data wire, note that there may be some "crossover" interference if the data wire follows a power wire for very much distance. It's usually not a problem to cross a conduit and tie to it, but it's generally recommended that you not tie data cable to conduit.
A grounding bar is most often located in the breaker panel. This is where all your grounding conductors are landed. If the panel is your primary service panel, neutrals and grounds can both be landed there. The NEC (US) requires that all service equipment be bonded together. This includes your meterbox. To most people bonding and grounding look alike but they serve different purposes. In most cases this bonding consists of a #6 AWG solid copper conductor connecting your service panel to your meterbox and also whatever you happen to be using as a grounding electrode, usually a water pipe and ground rod. Consult a competent electrician for what is required in your area. I was on a job once where the city inspector expected this bonding conductor to be run with the service conductors inside the same conduit, which is what I would expect. But the power company for the same job required it to be run outside the conduit which is acceptable practice. Both were right, but we had to do it one way for the inspection and another way before power was supplied.
It is a safety measure for devices that have a metal case where a failure in the device could cause the case to be connected to the hot side of the circuit. By grounding the case the breaker will trip instead of you getting a shock.
This is one of those questions that has a lot of answers! In a residence I would want it as short as possible, however you can legally run it 10 feet, if you use steel flex or metallic liquid tite in your raceway system the maximum length of the flex can only be 6 feet with the remaining 4 feet of conduit. Inspectors in some areas like for the service panel located in the first stud bay available nearest the service entrance, this usually keeps the conduit and wire length to a minimum.

Conduit wiring is simply wiring that you find in a conduit. Typically, a conduit is a small round tube, usually metal but sometimes plastic, that carries wires from one area to the next. Wire has a tenancy to sag and get tangled and such when it is laid out in long distances. The conduit serves to protect the wire and to ensure it stays linear and it stays in place.
Not usually. The emergency light wiring is using DC voltages and should not be mixed with AC wiring. In some installations the raceway will have barriers. Separation of DC, instrumentation and power cables is allowed if the raceway has barriers installed, and are used for these separate types of wiring.
PVC stands for Poly Vinyl Chloride. It is the chemical compounds that make up plastic. In short PVC conduit is plastic pipe that is used in the electrical trade. The lengths are glued together with PVC glue and usually used for underground electrical systems. It comes Schedule 40 and Schedule 80 (thicker) and comes in the same sizes as metal conduit Electrical PVC conduit is usually grey; plumbing PVC pipe is usually white
It does, with a reduced service. Some stations are usually closed, others may have their access restricted to a single entrance/exit or two.
The Bosporus Strait in Istanbul is usually considered the entrance to the Black Sea.

A #14 copper conductor is rated at 15 amps.
A tee joint in the electrical trade is a conduit fitting. It is used in conduit work where there needs to be a device connected into the main conduit run. An example of this is where a light switch needs to be installed into the conduit run. The main conduit run starts at the distribution panel and proceeds to a lighting fixture. On the way a switch is needed to operate the light fixture. In the main conduit run a tee fitting is installed so as to pick up the switch for the fixture. When the conduit system is complete the wire is then drawn in. The "hot" conductor is pulled to the tee fitting and then diverts to the switch box to pick up the switch and then back up the same conduit to the tee fitting and then on to the lighting fixture. Splices are not usually made in tee fittings.
A cave entrance is commonly referred to as a cave mouth or cave opening.
