A vertical plate and a horizontal plate are suspended in an
open room. Both are heated to the same temperature. Which one
will cool first?

Answer Posted / vivek

I think horizontal one.
Becoz cooling will occur due to natural convection. As the
horizontal plate will have more upper surface, so more heat
will go up in the form of air as it is a law of convection.
so it will cool faster than vertical.
