Mass

Explanation:

They physical property that is not the same among the four objects is their masses.

Mass is the amount of matter contained in a substance.

  • Specific heat is the amount of energy needed to raise the temperature of 1g of a substance by 1k.
  • Since the materials are made of the same metal, they have the same specific heat.
  • They will also have the same magnetism and electrical conductivity.
  • These properties are intensive property and do not depend on the amount of matter present.
  • Mass is an extensive property that depends on the amount of matter present.
