• # question_answer 41) A bucket full of hot water is kept in a room and it cools from ${{75}^{o}}C$ to ${{70}^{o}}C$ in ${{T}_{1}}$ minutes, from ${{70}^{o}}C$ to ${{65}^{o}}C$ in ${{T}_{2}}$ minutes and from ${{65}^{o}}C$ to ${{60}^{o}}C$ in ${{T}_{3}}$ minutes. Then                A)  ${{T}_{1}}={{T}_{2}}={{T}_{3}}$             B)  ${{T}_{1}}<{{T}_{2}}<{{T}_{3}}$C)  ${{T}_{1}}>{{T}_{2}}>{{T}_{3}}$                D)  ${{T}_{1}}<{{T}_{3}}<{{T}_{2}}$

More the initial temperature more is the rate of cooling. Hence. ${{T}_{3}}>{{T}_{2}}>{{T}_{1}}$                            or The rate of cooling decreases with decrease in temperature difference between body and surrounding.
