You can put this solution on YOUR website! Boiling water, at 100C is placed in a freezer at 0 degree celsius. The temperature of the water is 6 degree celsius after six minutes. What is the temperature after 2 hours?
At time zero the temperature is 100C: (0,100)
At time 6 min. the temperaure is 6C; (6,6)
EQUATION:
Temp = [(100-6)/(0-6)](time in min.)+100
Temp = 96/(-6)t+100
Temp = -16t+100
Temp(2hr) = Temp(120 min)= -16(120)+100= -1820C
