Analyzing +4 | -1

A sphere, a cube and a thin circular plate are heated to the same temperature. All are made of the same material and have the equal masses. If

t_1, t_2

and

t_3

are the respective time taken by the sphere, cube and the circular plate in cooling down to a common temperature, then

View answer and explanation

Correct option: A

t_1 > t_2 > t_3

Option B (

t_1 < t_2 < t_3

) is correct because the sphere has the smallest surface area for a given mass, and the circular plate has the largest.
