It depends on the particular rock and on the particular solid. Please restate the question, giving more specifics, such as what rock and what solid.
No. Molten rock expands due to heat as the molecules get excited, therefore it is less dense than solid rock.
No. Magma varies in density, but it will be less dense than a solid rock of the same composition.
rock is denser than gas because it is a solid
Yes. It is about as dense as solid rock.
a solid is more dense
Mafic rock is on average more dense.
No. It is less dense.
No. It gets less dense
More dense. As a solid is formed the particles vibrate less and group closer together. One of the only exceptions to this is water. When water freezes and becomes a solid it becomes less dense which is why ice will float in your drink.
Liquid magma is more dense than the solid material around it.
Less dense. For most substances, the solid form is more dense than the liquid form; water is a notable exception.Less dense.

If more dense, it will sink when put into water; if less dense it floats.
