(click on SI once there for SI units if needed). If you need higher pressure than 400psia or 16MPa, you will need the R143a superheated vapor chart, which I can't find online. You can find tables and charts in various thermodynamics textbooks. For example, Tables in "fundamentals of engineering thermodynamics" by Moran and Shapiro; or the chart by "SUVA/DuPont" is in the appendix of the "mechanical engineering reference manual" by Lindeburg.
First of all, the term "superheated" generally refers to a vapor. This explanation refers to superheated vapor only. Superheat is the difference (in degrees of temperature) between a liquid's boiling point and the superheated vapor's actual temperature. For example; at sea level, the boiling point of water is 212ºF. As long as the temperature is 212ºF, you will have both liquid and vapor present. If you continue to add heat to the liquid/vapor mix, all the liquid will eventually become vapor. Additional heat added after no liquid remains will begin to increase the temperature above 212ºF. This resulting vapor is superheated. If you measure the temperature of water vapor to be 220ºF at 1 ATM, the vapor is superheated by 8ºF. The same analysis is true for any liquid/vapor, at any pressure and for any other temperature scale. i.e. R22 refrigerant is "saturated" (meaning both liquid and vapor are present) at 32ºF and 58PSIG. If you measure the pressure of R22 at 58PSIG but measure the temperature at 45ºF, you have measured 13 degrees of superheat. I hope this answer is useful to you. Bama Cracker Degree of superheat is the difference between the superheated temperature and the saturated temperature of the steam .
A metal clad heating element 8 mm in diameter and emissivity ɛ = 0.95 is horizontally submerged in a water bath. The surface temperature of the metal is maintained at 250°C under steady state conditions. Estimate the power dissipation per unit length of the heater. Assume the water is exposed to atmospheric pressure and is at a uniform temperature.

That is experimental data and it is tabulated in Perry's Chemical Engineering Handbook and other places, check under "superheated water vapor." You might have to interpolate.

superheated vapor is a vapor that has been heated above its boiling point.
it remains in a vapor state
becaause it was just compressed by the compressor and is the high side of the system before the tex valve
superheated vapor
Refrigerant enters a direct expansion evaporator as a saturated liquid vapor mix and leaves as a superheated vapor.
In the natural environment, probably in geysers which, because of their pressure, contain superheated steam.
No, the sun is a ball of superheated matter called plasma. It doesn't have any solid properties.

No, superheated steam gives off little energy. Most of the heat given off by steam is the latent heat of condensation as it undergoes a phase change from vapor to liquid. Superheated steam could first be "desuperheated" by adding water until it reaches the saturation point, then used for heat transfer processes.
