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

Both 1 kg of feathers and 1 kg of lead have the same mass, which is 1 kilogram. However, feathers have a much lower density than lead, meaning that 1 kg of feathers will occupy a significantly greater volume than 1 kg of lead. Therefore, 1 kg of feathers has a greater volume than 1 kg of lead.
The weight of a body in air is its apparent weight because the body body remains immersed in air . Therefore apparent weight of 1kg cotton and one kg iron is same .But volume of 1 kg cotton is greater than the volume of 1 iron
No.
Neither!!! They both have the same mass at 1 kg. However, the feathers will occupy a greater volume.
1 kg is not a volume. It's a 'mass'.If the volume of a sphere is 1 cubic unit, then its diameter is 1.2407 unit (rounded).
