A solid cube and a solid sphere of the same material have equal surface area. Both are at the same temperture 120°C , then
a) the sphere cools down faster than the cube
b) both the cube and the sphere cool down at the same rate
c) the cube cools down faster than the sphere
d) whichever is having more mass will cool down faster
Answer »Answer: (c)
Rate of cooling of a body R = ${Δϴ}/t = {Aɛσ(T^4 - {T_O}^4)}/{mc}$
⇒ $R ∝ A/m ∝ \text"Area"/\text"Volume"[m = ρ×V]$
⇒ For the same surface area. $R ∝ 1/\text"Volume"$
Since Volume of cube < Volume of a sphere
⇒ $R_{cube} > R_{Sphere}$
i.e., the cube cools down at a faster rate.
