A hot cup of coffee is 200F when poured and placed in a room that is 70F. 10 min later the temperature of the coffee has cooled
Marianna [84]

Answer:

The temperature of coffee becomes 163.08 Fahrenheit.

Step-by-step explanation:

The Newton's law of cooling can be mathematically written as

-\frac{dT}{dt}=k(T-T_{room})\\\\\frac{-dT}{(T-T_{room})}=kdt

Applying the limits in the above relation as

At t = 0 ; T= 200 F

At t =10 ; T = 180 F

-\int_{200}^{180}\frac{dT}{T-70}=\int_{0}^{10}kdt\\\\-ln(T-70)_{200}^{180}=k\times 10\\\\\therefore k=\frac{ln(1.181)}{10}\\\\\therefore k=0.0167

Applying the limits in the above relation as

At t = 10 ; T= 180 F

At t =20 ; T = T F

-\int_{180}^{T}\frac{dT}{T-70}=\int_{10}^{20}0.0167dt\\\\-ln(T-70)_{180}^{T}=0.167\\\\\therefore T = 163.08F
