Question

physical change and particles
describe what happens to particles during a physical change by completing the sentences with the words from the box.
all matter is made up of tiny particles called. in elements, the atoms are all the, such as carbon, oxygen, iron, or gold. in, atoms of are bonded together to form molecules or lattices.
an iron nail is made up of
is an example of a compound. it is made up of hydrogen and oxygen atoms to form water (h₂o) molecules.
when a physical change occurs to a compound, the molecules, but the bonds that hold them together are not broken and so the remain after the change.
different types same type iron atoms change their position or motion
compounds water atoms same number and type of molecules

Explanation:

All matter is composed of atoms. In elements, atoms are of the same type. In compounds, different - type atoms bond. An iron nail is made of iron atoms. Water is a compound. During a physical change in a compound, molecules change position or motion but the number and type of molecules remain the same as bond - breaking doesn't occur.

Answer:

All matter is made up of tiny particles called atoms. In elements, the atoms are all the same type, such as carbon, oxygen, iron, or gold. In compounds, atoms of different types are bonded together to form molecules or lattices. An iron nail is made up of iron atoms. Water is an example of a compound. It is made up of hydrogen and oxygen atoms to form water (H₂O) molecules. When a physical change occurs to a compound, the molecules change their position or motion, but the bonds that hold them together are not broken and so the same number and type of molecules remain after the change.
