How does particle theory relate to pure substances?
Particle theory explains that all matter is made up of tiny particles. In the case of pure substances, these particles are the same throughout the substance, giving it a uniform composition. This understanding helps in identifying and describing the properties of pure substances based on the behavior of their particles.
Does a pure substance only have one type of particle?
Yes, a pure substance is a substance that is made up of only one type of particle. This means that all particles in a pure substance are identical in terms of their chemical composition.
is tap water in a glass pure substances or mixture?

Is the particles of a pure substance different?
No, the particles of a pure substance are all the same kind. In a pure substance, such as an element or a compound, the particles are identical in their chemical makeup. This is what distinguishes a pure substance from a mixture, where different substances can be present in varying proportions.
Why the separation of substances is necessary?
it is important to separate and purify substances so that: 1.we can get them in their pure form. 2.to remove undesirable particles from them.
What is a mixture of very tiny particles of pure substances that are dispersed in another substance that do no settle?
A colloid is a mixture in which very tiny particles of pure substances are dispersed in another substance, such as a liquid or gas, and do not settle out due to their small size and the constant motion of the particles. This results in a stable dispersion that appears homogeneous at first glance.
