Why is 1cm3 of wood lighter than 1cm3 of iron?
What is this mean is iron the space between iron molecules in iron much less than as that of wood. More molecules means more mass, that’s why iron is much heavier than wood for same volume.
Which is heavier iron or wood?
The masses of the atoms and the spacing betweeen them determine the density of materials. Density is considred as the ‘lightness’ or ‘heaviness’ of material of same size. Thus, iron is denser than wood (provided we consider the amounts of iron and wood to be the same). …
Why cotton is lighter than iron?
Answer 1 The iron bar is heavier than the bag of cotton. This is because the surface area of the cotton bag is larger than the iron bar. Hence, more buoyant force acts on the bag than that on an iron bar. This makes the cotton bag lighter than its actual value.
Why is wood less dense than water?
Wood is less dense than water. This means that particles of water are more close together than particles of wood. And so the kinetic energy of water particles should be less than the kinetic energy of wood particles.
Why is it incorrect to say iron is heavier than wood?
Why is it incorrect to say iron is heavier than wood? It depends how much iron and wood you have. You should say iron is denser than wood. of 1024 kg/m3.
What is heavier 1kg iron or 2kg cotton?
If you check carefully, both are of the same weight as they weigh but, cotton occupies more space than iron i.e. volume of 1 kg cotton is greater than that of 1 kg iron.
How cotton is heavier than iron?
The cotton bag’s density is less than that of the iron bar, so the volume of the cotton bag is more compared to the iron bar. So the cotton bag experience more upthrust due to the presence of air. Therefore, in the presence of air, the cotton bag’s true weight is more compared to the true weight of the iron bar.
What is another word for less dense?

What makes wood less dense?
What changes the internal energy of a stone?
Explanation: There will be no change in the internal energy of the stone, since this would only occur if there was some type of change of state of the stone (due to phase change, pressure or something of that nature).
Which is heavier 1kg cotton or 1kg gold?
Both will have same mass, but different volume ,as they have different density. Cotton ball will have more volume while having 1 kg mass than 1kg mass of gold.
