The temperature of
water 20 minutes after heating depends on its elevation and quantity of water
being boiled. The temperature of boiling water is lower at high elevation and
the more water you put on the kettle, the longer it boils. Approximately, 20
minutes after heating water, the temperature already reached 120 degree Celsius
for it takes 35 minutes to achieve the boiling point of water, which is 100
degrees Celsius.
