Question:medium
Hot water in a vessel kept in a room, cools from \(70^\circ C\) to \(65^\circ C\) in \(t_1\) minutes, from \(65^\circ C\) to \(60^\circ C\) in \(t_2\) minutes and from \(60^\circ C\) to \(55^\circ C\) in \(t_3\) minutes. Then
Hot water in a vessel kept in a room, cools from \(70^\circ C\) to \(65^\circ C\) in \(t_1\) minutes, from \(65^\circ C\) to \(60^\circ C\) in \(t_2\) minutes and from \(60^\circ C\) to \(55^\circ C\) in \(t_3\) minutes. Then
Show Hint
Cooling slows down as object approaches room temperature.

- \(t_1 t_3\)
- \(t_1 = t_2 = t_3\)
- \(t_1 > t_2 > t_3\)
- \(t_1 > t_2 = t_3\)
- \(t_1 < t_2 < t_3\)
Show Solution
The Correct Option is
