# Does high heat make a boiling pot of water evaporate faster?

According to another answer, the rate at which water evaporates depends on

the temperature of both air and water, the humidity of the air, and the size of the surface exposed.

The air temperature, humidity, and surface area are all essentially constant. The water temperature is too–roughly 100ºC, right?

So am I correct in thinking that whether I set my stove to medium or high, as long as the water is boiling, the evaporation rate is constant?

$$t = \frac{2257\ kJ}{2\ kW} \approx 1000\ \text{seconds}$$ which is about fifteen minutes. In fact you need more time than that because of all the energy losses through radiation, diffusion in surrounding materials...
