Given

• Kareem heats a beaker of water to a boil.
• then he records that the water temperature decreases from hundred degree to 19 degree in 5 - 2 / 5

Required to Find

Average change in temperature each 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 deg C /min
