100°CThe degree of hotness is defined by its temperature. When the water is boiling its temperature is 100°C(373.15K) under atmospheric pressure. After that the heat provided is latent heat which only changes the phase of the water (to steam). So the temperature of steam formed is also 100°C unless the steam is superheated.

Why does boiling water stay at 100 degrees?

The reason water boils at 100 C (at one atmosphere pressure)is that at this point, the molecules on average have enough energy to break the inter-molecular bonds holding the water together. As the pressure increases, the molecules need more energy- and so need to be at a higher temperature- to break free.

What bacteria can survive boiling water?
