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 :
From Newtons law of cooling, when a hot body is cooled in air, the rate of loss of heat by is the body is proportional to the temperature difference between the body and the surrounding, Hence, \[{{t}_{1}}<{{t}_{2}}<{{t}_{3}}\]You need to login to perform this action.
