In this case, we'll have to carry out several steps to find the solution.
Step 01:
Data:
chemistry lab:
initial temperature = 25 °C
rate = 2 °C / min
Step 02:
equation:
temperature of the solution (12 min):
T = temperature
t = time
T(t) = 25 + 2t
t = 12 min
T(12) = 25 + 2(12) = 25 + 24 = 49
The answer is:
The temperature of the solution after 12 min is 49°C
