What is denser liquid silver or solid silver?

Solid silver is denser.

Remember in a solid the atoms are closely packed and in a regular order.

When it is a liquid the atoms are less closely packed an in an irregular order.

Since liquid atoms are less closely packed, the same number of atoms occupy a larger space/volume.

Since they occupy a larger volume for the same number then liquids arr less dense.

Density = mass/ volume.

Solid ; Using 1 gram (Silver) occupies say 0.25 cm^(3) of space

Liquid ; using 1 gram(silver) occupies say 0.255 cm^(3) of space.

Hence

Density (Solid) =- 1/ 0.25 = 4 g/cm^(3)

Density (Liquid) = 1 / 0.255 = 3.91,,, g/cm^(3)

These are fictitious figures , just given to demonstrate.

Also , remember when a mass gains energy it changes from solid to liquid and EXPANDS(Greater volume/space).

So a block of solid silver , when placed in liquid silver will sink, because it is more dense.
