The answer depends primarily on the scale that you are using. On the Celsius (or Centigrade) scale, under normal atmospheric pressure, pure water boils at 100 deg.
The boiling point of water decreases with altitude, so the temperature at which water boils would be lower at a Himalayan peak compared to the seashore. This is because air pressure decreases with increasing altitude, which affects the boiling point of water.
120-160 Degrees Fahrenheit
Water heaters typically heat water to temperatures between 120 to 140 degrees Fahrenheit.
To sterilise effectively the water in the autoclave needs to reach a temperature of 120°C. Since water at atmospheric pressure boils at 100°C, a higher pressure is needed to reach that temperature.
Water boils at 212 degrees Fahrenheit at sea level.
At 0,5 bar water boils at about 176 °F or 80 °C At 1 bar water boils at about 212 °F or 100 °C At 2 bar water boils at about 250 °F or 120 °C See the link below for a graph, a table and an explanation.

When water changes from 80°C to 120°C, it transitions from being very hot but still liquid to reaching its boiling point and turning into steam. At 100°C, water boils and changes state from liquid to gas. So, by increasing the temperature from 80°C to 120°C, you are essentially bringing the water to its boiling point, causing it to evaporate into steam.
How hot and how fast? 5,000 btu's will heat it. Not very hot and it will take forever. If you are using it for residential hot water application. Roughly 40,000 BTU's
To calculate the total heat energy needed, you'd first need to raise the temperature of the water from 50°C to 100°C using the formula: Q = mcΔT, where Q is the heat energy, m is the mass (10 kg), c is the specific heat capacity of water, and ΔT is the temperature change. Then, you'd calculate the heat energy needed to change water at 100°C to steam at 120°C using the heat of vaporization formula: Q = mL, where L is the latent heat of vaporization of water. Add both calculated heat energies to get the total heat energy required.
