SUMMARY
Newton's Law of Cooling predicts the rate of temperature change of an object in relation to the ambient temperature. In the discussion, a container of hot water at 80°C cools to 79°C in 15 seconds in a room at 20°C. Using this data, the time required for the water to cool from 70°C to 69°C and from 30°C to 29°C can be estimated using the formula derived from Newton's Law of Cooling. The initial calculation of 18.75 seconds was identified as incorrect, emphasizing the need for accurate application of the law.
