Kelly has a sample of an unknown substance. Which properties of the substance will be the same no matter how large or small her sample is?

melting point boiling point
solubility mass
conductivity density

all of these
melting point, boiling point, and mass
melting point, boiling point, conductivity, density
melting point, boiling point, conductivity, solubility, density

bro i love how no one has the answers to basically any of these questions :,]

The properties of a substance that remain the same, regardless of the size of the sample, are melting point, boiling point, and density.

The properties of a substance that will be the same no matter how large or small the sample is are its melting point, boiling point, conductivity, and density.
