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.
