The minimum temperature for steam is 100c but is there a maximum temp? So by ‘steam’ you mean water gas right? Well 100 ºC isnt actually the minimum temperature for steam. It is the minimum temperature at standard atmospheric pressure, but under different conditions you can have steam down to even -50 ºC.

However, the zero point in the Kelvin scale is defined as the coldest possible temperature, known as “absolute zero”. Absolute zero is –273.15° C or –459.67° F. Instead of saying a temperature is “300 degrees Kelvin”, we say the temperature is “300 kelvins”.

Kelvin to Celsius conversion table

Water Hotter Than Boiling Point and Colder Than Freezing Point. Liquid water can be hotter than 100 °C (212 °F) and colder than 0 °C (32 °F). If water is superheated, it can exceed its boiling point without boiling.

about 100 degrees Fahrenheit

Steam that is saturated or superheated is invisible; however, “steam” often refers to wet steam, the visible mist or aerosol of water droplets formed as water vapour condenses.

Water illustrates the three states of matter: solid (ice), gas (steam), and liquid (water).

100 °C

Superheated steam is steam at a temperature higher than its vaporization point at the absolute pressure where the temperature is measured. Superheated steam and liquid water cannot coexist under thermodynamic equilibrium, as any additional heat simply evaporates more water and the steam will become saturated steam.

Q: Is it true that water (steam and ice) can not get hotter than 212 degrees and colder than 32 degrees? It is not true that water can only get up to 212 degrees and as cold as 32 degrees. After water changes from a liquid to a gas (at 212 degrees Fahrenheit) it can actually heat up much hotter than that.

In fact, superheated water-derived steam has so much energy stored within it that it can actually be used to start fires!
