Answer:
When the temperature of the coffee is 50 °C, the time will be 20.68 mins
Explanation:
Given;
The initial temperature of the coffee T₀ = 95 °C
The temperature of the room = 21°C
Let T be the temperature at time of cooling t in mins
According to Newton's law of cooling;
When the temperature is 50 °C, the time t in min is calculated as;
Therefore, when the temperature of the coffee is 50 °C, the time will be 20.68 mins
