Why does 1kg of iron have less volume than 1kg of cotton wool?
Cotton wool is less dense than iron, meaning it takes up more space for the same mass. Iron is much denser and therefore occupies less volume compared to the same mass of cotton wool.
Which denser 1kg of gold or 1kg of copper or 1kg of ironwhy?
Gold is denser than copper and iron. This is because the density of a material is determined by its mass per unit volume, and gold has a higher atomic mass than copper and iron, making it denser. So, 1kg of gold would occupy less volume compared to 1kg of copper or iron.
Is 1kg bigger less than 750g?
There are 1000g in a kg so 1kg is greater than 750g(.75kg).
Is 0.14kg more than 1kg?
No, 0.14kg is less than 1kg.
Which do you think contains more matter and occupies more space 1kg of iron or 1kg of cotton?
1kg of iron contains more matter and occupies less space than 1kg of cotton. Iron is denser than cotton, so it has a higher mass-to-volume ratio.
How do you check prediction that a sheet of paper has a mass less that 1 kilogram?
To check if a sheet of paper has a mass less than 1 kilogram, you can use a scale. Place the sheet of paper on the scale and ensure it registers a mass less than 1 kilogram. If the scale reads a mass of less than 1kg, then the prediction is accurate.
What causes negative buoyancy?
Negative buoyancy occurs when an object displaces less than its mass of whatever its not floating in. A liter of water has a mass of 1kg, but displaces less than 10g of air, so water sinks in air.
Can one material weigh less than another but have greater mass?
the Weight of an object is the force gravity exerts on it. So if you take a 1kg mass, on earth it pushes down 9.8n. but on say, the moon, you could take a 2kg mass, the amount of force it exerts downwards (the weight) would be less then the 1kg does on earth. So yes, but not if they are in the same place!
How much less than 1kg is each of these weight 850g 700g 550g 350g 175g25g?
1 kg = 1000g ⇒ 850g is 1000g - 850g = 150g less than 1kg ⇒ 700g is 1000g - 700g = 300g less than 1kg The rest are left as an exercise for the questioner.
Is 500g more or less than 1kg?
Convert everything to grams, or everything to kilograms, then you can easily compare it. (1 kg = 1000 grams) 500g is 0.5kg, so it is less than 1kg.
What is the greater volume 1kg of copper or 1kg of gold?
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.
Is 1kg feathers equal to 1kg stones?
Yes, 1kg of feathers is equal in weight to 1kg of stones. However, since feathers are less dense than stones, the volume of 1kg of feathers will be much larger than the volume of 1kg of stones.
