all of these
all of these
melting point, boiling point, and mass
melting point, boiling point, and mass
melting point, boiling point, conductivity, density
melting point, boiling point, conductivity, density
melting point, boiling point, conductivity, solubility, density
The properties of the substance that will be the same no matter how large or small her sample is are the melting point, boiling point, and mass.
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, and mass. These properties are intrinsic to the substance and do not depend on the quantity of the sample. Therefore, the correct answer is "melting point, boiling point, and mass."
Melting point, boiling point, and mass will be the same no matter how large or small Kelly's sample of the unknown substance is.
