Uhhh, boiling water is steam. That's, in fact, the DEFINITION of steam (water at or above the boiling point temperature / at or below the boiling point pressure). If it wasn't boiling, we'd call it water. read more

If both are at atmospheric pressure (14.7 psia), they are both at the temperature of 100C or 212F. So no, there is no difference in temperature. read more

Water only boils at 100 degrees At Sea Level steam is water with more energy in it so it is hotter than boiling water, (superheated water) also steam is far more likely to scald dangerously, it is as steam condenses that it releases energy. read more

Steam occurs when water goes above 212 degrees Fahrenheit, which is hotter than water when it is at its stable point. While water boils at 212 F, steam is at a much higher temperature as water turns to vapor. read more
