How does the density of a 100-kg iron block compare with the density of an iron filing?
The density of iron is 7,874 kg/m3 or 7.874 g/cm3. The density of iron filing is somewhat lower depending upon how fine the filings are, but I guess more than 4000 kg/m3 or 4.0 g/cm3. The SI standard of density is measured in kg/m3. The density of a material is defined as its mass per unit volume. The density of iron does not change with the size of the sample. A bucket full of iron filings will have a lower density than the block because there will be air between the individual filings. The density of a deep pile of filings will be greater than a thin pile because the weight of the filings above compacts the filings below by pushing out some of the air. However, the density of each individual piece will still be the same as for the whole block.
What does a magnet have for iron?
Yes, iron does have magnetic properties as well as the other two elements in the Iron Triad, Cobalt and Nickel.
In a physical change some of the substances in a material change but the properties if the material stay the same?
Yes, in a physical change, the arrangement or state of the particles in a substance can change, but the chemical composition and fundamental properties remain the same. Examples of physical changes include changes in state (solid to liquid), size, shape, or phase transitions.
Characteristics that describe how all matter is the same is called?
The characteristics that describe how all matter is the same are known as physical properties. These include properties such as mass, volume, density, and temperature, which are applicable to all types of matter.
What reaction of matter will stay the same during a physical change?
The chemical composition of the matter will stay the same during a physical change. Only the physical properties, such as shape, size, or phase, will be altered without affecting the chemical composition of the substance.
Does the iron in the mixture have the same or different properties to the element iron?
Iron keeps its unchanged chemical properties, but in a mixture it might add new, mostly physical properties to the alloy, this is also true for the other elements in the mixture, eg. C or Ni, or Cr in steel alloys.
Hammering hot iron into a sheet chemical or physical change?
Hammering hot iron into a sheet is a physical change. The process involves changing the shape and size of the iron without altering its chemical composition. The atoms in the iron remain the same, only the physical properties are altered.
Does chemical and physical properties are probably the same?
No. Chemical and physical properties are different.
Is iron filings and sand a compound or an element?
compoundIf the iron fillings are pure, they contain only one type of atom (all the atoms have the same number of protons). Thus, the filings would be a sample of the element iron. If the filings are rusty, then they would contain compounds (iron oxides).
What is a example of two items of different size having the same physical properties com?
For example two different (as size) nails made from the same iron alloy.
Is isotopes of same element have same properties?
The differences in chemical properties are not significant (excepting protium and deuterium); the physical properties are different.
Why do iron filings do not sink when placed slowly on the surface of the water?
Iron filings are typically made up of very small particles with a low density, allowing them to stay afloat on the water's surface due to surface tension. The small size and shape of the filings prevent them from sinking immediately and enable them to be suspended on the water's surface before gradually sinking as the surface tension weakens.
Is an atom of iron the same the same as atom of oxygen?
An atom of iron has 26 protons. An atom of oxygen has 8 protons. The atoms are significantly different.
What elements are similar to iron?
What elements are similar to iron in a chemical property on the Periodic Table
What should be similarities among homologies?
Homologise have the different molecular masses so can not have the same physical properties, due to same functional group they show same chemical properties but with different rates of reaction.
What do you need to know if you have two compounds of iron and chlorine to know they are the same compound?
To determine if two compounds of iron and chlorine are the same, you would need to know their chemical formula. This will tell you the ratio of iron to chlorine in each compound. You may also need to analyze their physical properties, such as melting point or color, as an additional confirmation. Additional characterization techniques like spectroscopy may also help confirm their identities.
Do compounds of the same functional group have same physical properties?
Compounds with the same functional group can have similar physical properties, such as boiling point or solubility, due to similarities in their chemical structure and intermolecular forces. However, other factors like molecular weight or branching can also affect these properties.
