Yes.
Particle size would have much to do with it. The smaller the size of the single particle, the larger the difference between surface area (directly heated) to the volume that has to be heated.
Increase in radius affect the increase of the centripetal force on a particle in uniform circular motion. An increase in radius would cause a decrease in the force if velocity remains constant.

A circular disc ( like a nickel ) would have three surfaces.
When steel (or indeed anything) is heated its mass does not change. Volume is altered by cooling and heating. In this case the volume of the steel would increase.
I would call this convection currents in the mantle.
A cone would fit the given description

A sphere that has been sliced by a plane will have a circular base and a curved surface. In the special case that this plane goes through the centre of the sphere, the shape will be a hemisphere. in simple terms it would actually be a cone...
The pressure will increase
