An object initially at 60 degrees Celsius cools to 50 degrees in 5 minutes. Estimate the it will take so that the object will cool down from 50 to 44 degrees if the surrounding temperature is 32 degrees. Provide the numerical value of the time in minutes with 2 significant figures.An experimental sample was placed in an enclosure having a constant temperature. Its initial temperature is 80 degrees and after 5 minutes, it cooled down to 70 degrees. After another five minutes, the temperature of the sample dropped to 62 degrees. What is the temperature of the enclosure. Provide the numerical value of the temperature in degree Celsius, in three significant figures. Example: 23.5
