Use dT/dt = k(T-T0)
Where T is the temperature of the turkey, T0 is the temperature of the surroundings and k is a constant.
"Rate of change of temperature is proportional to difference between temperature of turkey and surroundings"
-Separate and integrate
-Use the provided info(155F after 1/2h) to find constant k
-Sub in values to get answer
A roasted turkey is taken from an oven when its temperature has reached 185°F and is placed on a table in a room where the temperature is 76°F.
(a) If the temperature of the turkey is 155°F after half an hour, what is its temperature after 45 min? (Round your answer to the nearest whole number.)
______°F
(b) After how many hours will the turkey cool to 100°F? (Round your answer to one decimal place.)
________hr
