Not all the solids will dissolve in water. Different solids have different solubilities (some will dissolve more than others). The higher temperature, the more will dissolve
An aloy is an example of a homogenous (metallic) solid mixture.
Mud is a solid not a liquid if you wanted to know :]
It is an alloy: a homogenous mixture of two (or more) metals. An 'single-phase solid-in-solid'-mixture.
This is a mixture solid-liquid or solid-gas.
'Solubility' . NB Different substances have different solubilities. NNB All Group 1 metals are soluble. All nitrates are soluble Most chlorides are soluble or partially soluble Sulphates are insoluble. NNNB There is a table of solubilities for different substances in Wikipedia.

Yes. The pastry is solid. The filling is mainly liquid, with a few solid chunks of apple in it. So that's a mixture of different states.
The gas and the solid are two different compounds, they won't be the same therefore they'd be a mixture.
dirt is a mixture
Trail-mix is a heterogeneous mixture: It contains visually different solid materials.
An example of a solid mixture is a metal alloy such as brass.
Steel is a homogeneous mixture, also referred to as an alloy. It is a solid-solid mixture of metals.
An aloy is an example of a homogenous (metallic) solid mixture.
Look at the position of Pb in the periodic table and the postion of the Alkali Earth metals. Alkali Earth Metals are in noble-gas configuration when they are doubly charged cations. Lead however is on the right hand side, and would like to have more electrons to get into that stablest configuration; making the bonds in lead-compounds more covalent -and stronger- in nature. Insoluble compounds have lattice enthalpies higher than the enthalpy of solvation. Now since Alkali Earth metals like to be in ionic states; their compounds will dissolve in general more easily than the same compounds with lead, since usually the lattice energy of lead compounds is much higher (In case of insoluble compounds higher than the energy that would be released upon solvation, which thus doesn't occur).
