A thermometer is removed from a room where the temperature is 70° F and is taken outside, where the air temperature is 8 F. After one-half minute the thermometer reads 47° F. How long will it take for the thermometer to reach 27 °F? Assume that the rate of change of temperature in time is proportional to the difference between the thermometer's temperature and the air temperature. Type your answer in minutes in the space provided below. Round your answer to two decimal places.

Entropy

In physics, entropy means the amount of disorder or the degree of randomness associated with a thermodynamic system. The system is not self-organized when the entropy of the system is high. For instance, when a system is at an elevated temperature, its molecules are in random motion, vibrating and colliding with each other. During this scenario, the probability of finding a molecule at a particular place twice, is low. Under this circumstance, the system can be said to be in a high entropy.
