Step 1: Given details
The rate at which a body’s temperature changes is directly proportional to the temperature difference between the body and its surroundings.
The formula for the Newton's law of cooling is expressed as
Here,T(t) is the temperature of the object at a certain time t
Ts is the temperature of the surroundings. To is the initial temperature and is the cooling constant.
Provided, temperature of the surroundings(Ts) is -12oC and initial temperature is 18oC(To)
After one minute the thermometer reads 9 degrees C. i.e.
