One kilogram. Mass is invariant.
The weight at that point is zero. But the mass doesn't change.
Yes.
on the surfaceNote:Since the earth's composition is not homogeneous, the gravitational acceleration onthe surface is probably less than what it is some small distance below the surface,but it's certainly greater than at the center.
there are a few places where magma come close to earths surface. Very expensive deep wells must be drilled to tap this energy.

No. This has not occurred, yet.
it flows because if convection currents
the temperature would greatly increse!1
