How long for water to boil to 100 fahrnheit?

Answer 1

The definition of 100 degrees Celsius is "the temperature at which water boils under a pressure of one standard atmosphere," so if it's boiling at that pressure it's ALREADY at 100 degrees C; no "minutes" are involved.

Also, if you're at less than one standard atmosphere (you're in Denver or something) the water is not going to reach 100 degrees C no matter HOW long you boil it.

Answer 2

It depends on how much water there is. Q = mlv , where Q= heat energy, m= mass of water and lv= latent heat of vaporization. Take note that P = Q/t, where P = power of the heat source and t is the time taken. When m increases, Q increases, and if P remains constant, t increases. Thus, it takes a longer time for water to boil when there is more water.

Surrounding pressure also affect the rate of boiling. Boiling occurs when the vapour pressure of water equals the surrounding pressure. When surrounding pressure is low, as in the highlands, the vapour pressure would be low too when boiling, and hence, it boils faster at higher altitudes. Conversely, it boils slower at lower altitudes.

Hope my answer helps, and pardon me if I'm wrong in any way. :)

Answer 3

The time it takes for water to reach 100 degrees Fahrenheit depends on factors such as the initial temperature of the water, the heat source, and the volume of water. In general, it can take a few minutes to reach 100°F when boiling water on a stovetop.
