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 Sun has a temperature ranging from 6,000Â° Celsius at its surface which is hot enough to turn gold, tungsten and every metal on Earth into gas. It is around 15,000,000Â° Celsius in its center-far hotter than anything we can generate on Earth. Pressure is also enormously high in its center.
