WitrynaWith known initial and ambient temperatures, you can use the T1 = A + Te^rt in two ways: if you know the rate of change AND the time, you can just plug both r and t into the equation to get T1 (the temperature you're looking for). What Sal did was just solve in the other direction; he used a known T1 to find the corresponding t. WitrynaAns. Integrate the differential equation of Newton's law of cooling from time t = 0 and t = 5 min to get. which gives b= (1/5)ln (7/5). Now, repeat the same for the time interval t=5 min to =τ in which temperature decreases from 70 ° C to 50 ° C. Substitute b and simplify to get τ =12.6 min.
