The water in the container has a temperature of t1 = 80◦C, the temperature around the container is t2 = 15◦C. The dependence of temperature t on time τ (in minutes) can be expressed approximately by the formula:
t = t2 +(t1 −t2)·e^(−0.05·τ)
Calculate the temperature of the water
a) after 5 minutes;
b) after 1 hour.
t = t2 +(t1 −t2)·e^(−0.05·τ)
Calculate the temperature of the water
a) after 5 minutes;
b) after 1 hour.
