all are elements solid at 25C except Bromine and Helium
Chemical- the composition of the substance Physical- appearance of substance
Color, freezing point, or even texture if the substance is solid.
How would you define a subtancebased on what you have obsrved
A precipitate is a solid that forms when two liquids mix together and a reaction causes a solid substance to appear. It appears as a solid that settles at the bottom of the container.

A solid substance that forms when two liquids are mixed is called a precipitate. This occurs when chemical reaction between the two liquids forms a new solid substance that is insoluble in the mixture.
At -25°C, wax would be in a solid state.

YES!!! In everyday impure form, it is limetstone, chalk, marble , egg shells. All of which are solids.
No, freezing is a change in STATE of a substance (from liquid to solid), the solid is NOT a new substance.
