To calculate: The cooling rate of the fudge.
Given:
Heating temperature,
Cooling temperature,
Time required by fudge to reach
Concept used:
From Newton’s law of temperature:
Where,
Calculation:
Rewrite the equation as follows:
Take the logarithms on both sides with a natural base;
Apply the power rule
Thus,
Substitute these values in the above equation(2);
Now,
Conclusion:
Hence, the required increased rate of cooling is
