When iron (Fe) rusts, it combines with oxygen (O2) to form various forms of iron oxide such as Fe2O3, Fe3O4, or FeO2. In each of these there are oxygen molecules bonded to the iron. The oxygen comes from the air, water or other solution. So an object which was formally pure iron, once rusted, will contain additional mass from the oxygen and weigh more than it did before.
Iron gains oxygen/water to become hydrated iron oxide -rust and so weighs more.
rust is iron oxide. so what's happening at the atomic level is oxygen is bonding to the iron. The iron stays with oxygen attached, the oxygen is the increased weight.
Powdered iron rusts more easily because the increased surface area allows for greater exposure to oxygen and moisture, which are the primary causes of rusting. The smaller particles of powdered iron have a larger surface area compared to solid iron, leading to a faster reaction with oxygen and water.
Rust is iron oxide, a molecule consisting of iron and oxygen. The mass of the iron in the rust molecules comes from the original nail, but the mass of the oxygen has come from the air. When rust forms on iron, the mass of the iron object is increased by the mass of the oxygen that has combined with some of the iron.
Speaking from a weight standpoint a pound of feathers weighs the same as a pound of iron. They each weigh 1 pound. However it take many more feathers to weight a pound then chunks (ingots) of iron.
Because of the pressure that is on the the hot iron the cold iron doesn't have as much force as the hot one so that's why!
A reaction occurs more quickly when powdered iron is used instead of a single piece of iron of the same mass because the powdered iron has a much greater surface area and all chemical reactions take place on surfaces.
I believe the mass is greater as rust is the combination of iron plus oxygen, similarly the smoke and ash from a fire, if collected, would weigh more than the fuel alone before it was burnt. strange but true. Ask a chemistry boffin to prove the maths.

The right question should be: Does one mole of iron weigh the same as one mole of iron oxide? The answer is NO, Iron Oxide weighs more.
because the iron bonds with oxygen, so the weight becomes the original weight of iron plus the original weight of Oxygen.
Depending upon conditions which might call for more exotic media, the most commonly used substances are powdered graphite and/or powdered iron filings.
Because iron is much more dense.
The iron the hasn't burnt will less than the one that has burn because the mass is goign more thicker because it is burning

If they are both a kilogram, then they both weigh the same.
