The Department of Energy recommends having your tank-based hot water heater set to 120 degrees Fahrenheit for most people, but if youâve never adjusted the temperature on your hot water heater, itâs probably set to 140 degrees, which is the default setting from most manufacturers.
Plasma is a state of matter in which all matter is ionized and it occurs in the form of ions and electrons. Since, we know that for the ionization of the element or matter to occur energy is required to pull the electron from the attraction of the nuclear charge, high energy is required.
Most matter in the universe is in the plasma state. Here are a few specific examples of plasmas: 1  Gases in discharge tubes (fluorescent lamps and neon signs). 2  Welding arcs. 3  Lightning. 4  Auroras. 5  The upper atmosphere (the ionosphere). 6  Stars and the Sun. 7  the solar wind. 8  interstellar gas clouds.
