A) \[{{T}_{1}}={{T}_{2}}={{T}_{3}}\]
B) \[{{T}_{1}}<{{T}_{2}}<{{T}_{3}}\]
C) \[{{T}_{1}}>{{T}_{2}}>{{T}_{3}}\]
D) \[{{T}_{1}}<{{T}_{2}}>{{T}_{3}}\]
Correct Answer: B
Solution :
[b] The time of cooling increases as the difference between the temperature of body & surrounding is reduced. So \[{{T}_{1}}<{{T}_{2}}<{{T}_{3}}\] (according to Newton's law of cooling).
