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: C
Solution :
According to Newton's law of cooling Rate of cooling µ Mean temperature difference Þ \[\frac{\text{Fall in}\,\text{temperature}}{\text{Time}}\propto \left( \frac{{{\theta }_{1}}+{{\theta }_{2}}}{2}-{{\theta }_{0}} \right)\] Q \[{{\left( \frac{{{\theta }_{1}}+{{\theta }_{2}}}{2} \right)}_{1}}>{{\left( \frac{{{\theta }_{1}}+{{\theta }_{2}}}{2} \right)}_{2}}>{{\left( \frac{{{\theta }_{1}}+{{\theta }_{2}}}{2} \right)}_{3}}\] Þ \[{{T}_{1}}<{{T}_{2}}<{{T}_{3}}\]
