Explanation:
Each different kind of atom represents an atom. Elements like atoms are considered to be distinct substances that cannot be split into simpler substances. Such substances are known to be made up of just one kind of atom.
Like an atom, elements are made up of protons, neutrons and electrons. Both the protons and neutrons are found in the nucleus of the atom.
A physical property is a property that does not change the original substance, meaning that it does not break any bonds, nor for any new ones. Though, a physical property can be changing the substances state of matter.
When you are boiling water, you are changing its state to go from a liquid to a gas. The temperature is not a characteristic physical property because it doesn't help us know a lot about that substance, in other words, it isn't significant to the substance. Same goes for volume.
A) 1 cm ---------- 10 mm
14 cm ---------- ?
14 x 10 / 1 => 140 mm
-------------------------------------------------------
b) 1 cm ----------- 0.00001 km
14 cm ---------- ?
14 x 0.00001 / 1 => 0.00014 km
