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 chromosphere is the second of the three main layers in the Sun's atmosphere and is roughly 3,000 to 5,000 kilometers deep. The chromosphere's rosy red color is only apparent during eclipses. The chromosphere sits just above the photosphere and below the solar transition region. The layer of the chromosphere atop the photosphere is homogeneous. A forest of hairy appearing spicules rise from the homogeneous layer some of which extend 10,000 km into the corona above. The density of the chromosp
