Intravenous therapy (IV therapy or iv therapy in short) is the infusion of liquid substances directly into a vein. Intravenous simply means within vein.
While the photosphere hovers around 5,800 kelvin, the temperature of the chromosphere varies between 4,500 K and 20,000 K. Even though itâs more distant from the center of the Sun, the chromosphere is hotter than the photosphere.he photosphere is the region of the Sun that we see. It measures an average temperature of almost 5,800 kelvin and produces the visible radiation. This is the point where photons generated inside the Sun can finally leap out into space. The chromosphere measures just 2,000 km, and itâs just outside the photosphere.
The temperature at the very center of the Sun is about 15,000,000Â° C (27,000,000Â° F) and the density is about 150 g/cmÂ³ (approximately 10 times the density of gold, 19.3 g/cmÂ³ or lead, 11.3 g/cmÂ³). Both the temperature and the density decrease as one moves outward from the center of the Sun. The nuclear burning is almost completely shut off beyond the outer edge of the core (about 25% of the distance to the surface or 175,000 km from the center).
