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.
Heat is produced in the process of the formation of Ozone and this heat is responsible for temperature increases from an average -60Â°F (-51Â°C) at tropopause to a maximum of about 5Â°F (-15Â°C) at the top of the stratosphere. This increase in temperature with height means warmer air is located above cooler air.
