A vessel full of hot water is kept in a room and it cools from `80^(@)C` to `75^(@)C` in `T_(1)` minutes, from `75^(@)C` to `70^(@)C` in `T_(2)` minutes and from `70^(@)C` to `65^(@)C` in `T_(3)` minutes Then .

Options

A. `T_(1) =T_(2) =T_(3)`
B. `T_(1) gt T_(2) gtT_(3)`
C. `T_(1)ltT_(2)=T_(3)`
D. `T_(1) lt T_(2) lt T_(3)`

Answer

D

Explanation

Rate cooling decreases with fall of temperature Hence, time increases .
