It depends on if they are solid or liquid.
aluminium
Neither!!! They both have the same mass at 1 kg. However, the feathers will occupy a greater volume.
Density = Mass/Volume. For water: 1/(1*1*1) = 1/1 = 1 g/cm3 For plastic: 4/(2*3*1) = 4/6 =2/3 g/cm3. So the water has the greater density.
No, a gram has a volume of 1ml.
It is because the buoyancy of water is greater than that of air. In other words, the force pushing up on an object is equal to the weight of the same volume of whatever the object is in as the volume of the object. For example, a 1'x1'x1' cube submerged in pure water has an upward force on it of 62.4 pounds because the density of water is 62.4 pounds per cubic foot.
Lead (11,34 g.cm^-3) has a greater density than water (1 g.cm^-3) so for the same volume of water and lead, lead will be heavier. The "-3" should be written as an exponent but it won't allow me
aluminium
Yes, on volume basis The volume of 19,3 milliters of water (or anything else) is greater than the volume of 1 milliliter of gold (or anything else)
Volume is the amount of 3-dimensional space occupied by an object and has nothing whatsoever to do with the molecular composition of the object. The volume of a 1" x 1" x 1" cube of lead is exactly the same as the volume of a 1" x 1" x 1" cube of butter or a 1" x 1" x 1" cube of anything for that matter. Lead and butter have a great many differences, but volume isn't a measure of any of them.
1 cup of water is the same volume as 1 cup of sand.
Water expands approximately 10% when frozen, so the water would have less volume than the ice.
Depends on the substance. A gram of lead will have a lot less than a ml of volume, while a gram of oxygen will have a greater volume than 1 ml. Water is 1 ml per gram, but that changes with the temperature of the water. Warm water, and very cold water (<4o C) will have a somewhat greater volume than 1 ml per gram weight.
A kilogram of butter as it is less dense than lead.
Neither!!! They both have the same mass at 1 kg. However, the feathers will occupy a greater volume.
The density of water is 1. With their peel on, the orange's density is less than 1. However, without the peel, the orange's density is greater than 1. Density > 1 (Float) Density < 1 (Sink) Mass ÷ Volume = Density Mass ÷ Density = Volume Density × Volume = Mass
For an object to flat it must displace more water than it weighs. So a 1 kg hollow steel ball bust displace 1kg of water. 1 kg of water has a volume of 1 litre so the steel ball must have a volume greater than 1l. Note: 1lite = 1000cm^3
Density = Mass/Volume. For water: 1/(1*1*1) = 1/1 = 1 g/cm3 For plastic: 4/(2*3*1) = 4/6 =2/3 g/cm3. So the water has the greater density.
