pyroclasic flow
A material that has a high resistance to the flow of electrons is an insulator.
Yes
No. Gas giants do not have a solid surface on which lava might flow.
Yes - a Newtonian fluid (or just a fluid) is one that continues to flow regardless or forces acting on it, and is only governed by temperature and pressure. Gas certainly 'flows' without the use of force: a gas will fill an unoccupied room without any external forces.
Because it has the ability to flow.
plasticity
liquid and gas because they both have an ability to flow
"Fluids" are substances whose particles are not rigidly attached to each other. Thus, they can flow.
In general, fluidity is the term used to refer to the ability of a fluid to flow. It's the reciprocal of viscosity, which is the resistance of a fluid to deform when subjected to either shear or extensional forces. It (viscosity) is often thought of as the "thickness" of a fluid.Consider that a gas is a fluid just as a liquid is, and a gas is "more fluid" than a liquid. It (the gas) has a greater ability to "flow" than a liquid. Gas atoms or molecules "stick together" less than the atoms or molecules of a liquid. We don't use the term fluidity much in engineering, but stick to viscosity, which is linked below.Solid:A solid's ability to flow is called plasticity. Examples of this process would be the earth's mantle, which is solid material that flows underneath the Earth's crust.
The property is called the material's "thermal conductivity".

Perhaps a "jet".
pyroclastic flow
The mantle is much hotter and has the ability to flow.
