Under standard conditions (25oC, 1atm), the density of air is about 1.168kg/m3. Hence 1kg of air would have a volume of: 1.168kg/m3 divided by 1kg = 0.8562m3
Residual volume is the amount of air left in the lungs after a maximal exhalation
Copper will have the larger volume because it is less dense than gold.
Without knowing the density of an object, it's not possible to calculate it's volume by weight. A 1kg piece of granite and a 1kg piece of igneous rock would be very different in volume.
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.
Because it is smaller in volume.
no, because density=mass/volume; 1kg of iron = 1kg of flour isn't? density only affected by the mass and its volume.
they're both one kilogram so....
Nooo, 1kg gold is heavier 1kg cotton, because the last one has much more volume than the first, so Archimedes force reduces weight of a cotton more!
