Whenever the sample masses are both on the same planet, 1 kg of anything
has the same weight as 1 kg of anything else.
Although the above answer is correct, 1 kg of cork would seem heavier because the weight is spread out. This makes it harder to balance, and would therefore require more energy.
Cork is lightweight, buoyant, and has insulating properties, while iron is dense, heavy, and a good conductor of heat and electricity. Cork is flexible, while iron is rigid. Cork is typically used in insulation, gaskets, and flooring, while iron is used in construction, machinery, and tools.
Density and melting point are different.
Because iron oxide is not iron and the chemical/physical properties of substances are different.
The three different bottles likely contain samples of iron nail treated with different substances or under different conditions to demonstrate different properties of iron. This allows students to observe how iron reacts under varying circumstances or to test hypotheses about its properties.
Because iron is rusting.

Iron sulfide is a chemical compound formed by iron and sulfur combining. It has unique properties different from its constituent elements, such as a distinct crystal structure, color, and chemical reactivity. Iron is a metal, sulfur is a non-metal, and iron sulfide is considered a compound with its own distinct properties.
Cork insulates, is water resistant and floats in water.
Wooden cork is less dense than the water and the iron is not.
Cork exhibits insulating properties. Not conducting.

Silver and iron have different properties because they have different atomic structures. Silver is a transition metal with strong metallic bonding and high ductility, while iron is also a transition metal but forms different crystal structures and exhibits magnetic properties due to its unpaired electrons. These differences in atomic structure lead to variations in properties such as conductivity, malleability, and strength.
Rust is a compound formed when iron reacts with oxygen in the presence of moisture or water. It has a different chemical composition and properties compared to pure iron or oxygen. Rust is a combination of iron oxide compounds which are brittle and flaky, unlike the malleable properties of iron and the gaseous nature of oxygen.
No, a cork is not made up of rubber. Cork is a natural material derived from the bark of the cork oak tree (Quercus suber). It is composed primarily of a substance called suberin, which gives it its unique properties, such as being lightweight, buoyant, and resistant to moisture. Rubber, on the other hand, is typically derived from the sap of rubber trees (Hevea brasiliensis) and has different chemical properties.
