Kareem heats a beaker of water to a boil then he record that the water temperature decreases from 100 degrees celsius to 19 degrees celsius in 5 2/5 minutes what was the change in temperature each minute

To solve for the problem, we list first all the given

Given:

Initial temperature, T1 = 100 degC
Final temperature, T2 = 19 degC
Time, t = 5 2/5 mins or 5.4 mins

Required: Change in temperature per minute

Solution:

Change in temperature per minute = (T1-T2)/t
Change in temperature per minute = (100 degC - 19 degC)/5.4 mins
Change in temperature per minute = 15 degC/min

ANSWER: 15 degC per minute
