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.
The 4th state of matter is plasma or ionized gases which can exist only at very high temperatures, where free particles consist of charged, usually in equal numbers, such as ions and electrons. Just like gaseous state, plasma is a state of matter does not have a definite shape or volume.
