Both 1kg of lead and 1kg of polystyrene have the same mass, despite lead being much denser than polystyrene. Density is defined by mass divided by volume, so if the mass is the same, the volume must differ to maintain the same density. In this case, the volume of lead will be significantly smaller than the volume of polystyrene, making them have the same density.
No, 1 kg of lead will take up less space than 1 kg of polystyrene because lead is denser than polystyrene. Density is the amount of mass per unit volume, so lead, being denser, will occupy less volume compared to the same mass of polystyrene.
Neither. Since they both have a weight of 1kg one cannot be heavier than the other.
1kg of gold and 1kg of iron weigh the same amount because they both weigh 1 kilogram. The difference between the two lies in their density and value, not in their weight.
No, both 1kg of lead and 1kg of feather would weigh the same in a vacuum because weight depends on mass, and both objects have a mass of 1kg. Gravity affects weight, but in a vacuum, there is no air to provide resistance, so both objects would fall at the same rate.
1kg of aluminum occupies more volume than 1kg of lead, as aluminum is less dense than lead. Densities of aluminum and lead are 2.7 g/cm³ and 11.3 g/cm³, respectively.

They both weigh the same: 1kg = 1kg. The kg of butter has a greater volume and the kg of lead has a higher density.

The lead and the copper will weigh the same. But there will be less lead than copper by volume if both materials are solids. And that's because lead is more dense than copper. A given volume of lead weighs more than that same volume of copper. It turns out that 1kg of something will weigh the same as 1kg of something else, though the two may have different volumes for that weight. A kg of lead takes up a lot less room (volume) than a kg of ping pong balls, even though they both weigh the same.
1kg of aluminum occupies more volume than 1kg of lead, as aluminum is less dense than lead. Densities of aluminum and lead are 2.7 g/cm³ and 11.3 g/cm³, respectively.
You're a total life noob, it depends on the density and molecular weight of the matererial. Which falls faster? a) 1kg box of feathers; or b) 1kg box of lead.
The volume of a substance is determined by its density and mass. Copper has a density of 8.96 g/cm³ and gold has a density of 19.32 g/cm³. Therefore, 1kg of copper would have a greater volume than 1kg of gold because copper is less dense than gold. In other words, the same mass of copper would take up more space than the same mass of gold due to their differing densities.
1 kg of lead has more volume And that's because lead is more dense than copper. A given volume of lead weighs more than that same volume of copper. It turns out that 1kg of something will weigh the same as 1kg of something else, though the two may have different volumes for that weight.
If both weight 1kg as in your question then they are the same. Some flour maybe stays in the package where it was maybe like 40-50 grams and you think there is a magic in this. They are simply equal.
The price of 1kg of lead can vary based on market conditions, but as of now it is around $1.00 to $1.50 per pound. So, 1kg of lead would cost approximately $2.20 to $3.30.
