Answer:
20°
Step-by-step explanation:
In 1 minute, change in temperature =(100-60)°=40°c.
Therefore,
If, the temperature of water is 20°,
temperature cooled down after 2 minutes =(40+40)°=80°.
therefore, now temperature =(100-80)°=20°
and in the third minute, temperature will not change as the water's temperature will not decrease.
(keeping water's temperature as a constsnt).
