They both weight a kilogram. Lead has a higher density.
Lead
Iron has a greater density.
if the substance of the element has greater density you can make it float by carving it out so weight over volume of the object is lighter in effective density
Density is a weight per unit volume calculation. There could be different alloys or casting methods with subtle differences in density, or temperature variations in expansion and density. However: Every cubic centimeter of lead weighs 11.34 grams. Every cubic centimeter of iron weighs 7.86 grams. Thus, the density of lead (11.34 g/cc) is greater than iron (7.86 g/cc). This is independent of the actual weight and volume of the sample.
Lead has a greater density than silver. Lead has a density of 11.34 g/cm3, while silver has a density of 10.49 g/cm3.
The mass of lead would be greater, as lead has a higher density compared to silver. Density is mass divided by volume, so even if both samples have the same volume, the lead sample would be heavier due to its higher density.
They both weight a kilogram. Lead has a higher density.
Lead
They both weigh the same: 1kg = 1kg. The kg of butter has a greater volume and the kg of lead has a higher density.
silver
Yes, by about 8.2%. (rounded)
No, lead is a dense material and will sink in water. The density of lead is greater than the density of water, so it will not float.
Solid silver is denser than liquid silver. The density of solid silver is around 10.49 g/cm^3, while the density of liquid silver is around 9.32 g/cm^3.
water has less density than lead. Mass depends on its volume
Lead weight sinks in water since its density is greater than that of water.
5 cm3 of gold would have a greater mass than 5 cm3 of silver because gold has a higher density than silver.
