A bucket full of hot water is kept in a room and it cools from

75^\circ \,C

70^\circ \,C

{T_1}

minutes, from

70^\circ \,C

65^\circ \,C

{T_2}

minutes and from

65^\circ \,C

60^\circ \,C

{T_3}

minutes. Then

View answer and explanation

Correct option: B

{T_1} < {T_2} < {T_3}

Option B (

{T_1} < {T_2} < {T_3}

) is correct because, according to Newton's law of cooling, the rate of cooling decreases as the temperature difference between the object and the surroundings decreases.
