Physics Question on Heat Transfer
A sphere, a cube and a thin circular plate all of same material and same mass initially heated to same high temperature are allowed to cool down under similar conditions. Then the
A
plate will cool the fastest and cube the slowest
B
sphere will cool the fastest and cube the slowest
C
plate will cool the fastest and sphere the slowest
D
cube will cool the fastest and plate the slowest
Answer
plate will cool the fastest and sphere the slowest
Explanation
Solution
Surface area is more for plate and less for sphere. Hence plate will cool the fastest and sphere the slowest.
