A substance that cannot be separated physically is a pure substance.
Solutions are mistaken for pure substances because they often appear uniform and have consistent properties throughout the mixture. However, solutions are actually a homogeneous mixture of two or more substances, where one substance (solute) is dissolved in another (solvent). This is different from a pure substance, which consists of only one type of particle.
"Pure" generally implies that the object has no unwanted material. It can include mixtures and solutions. For example, Ivory soap is advertised as being 99.9% pure meaning it has nothing in it that they didn't intend to put in the soap.
Both pure substances and solutions can evaporate, but they do so at different rates and under different conditions. Pure substances, such as water, will evaporate at a specific temperature and pressure, while solutions may evaporate more slowly due to the presence of solutes, which can lower the vapor pressure. The rate of evaporation depends on factors like temperature, surface area, and air movement, regardless of whether the material is a pure substance or a solution.
Substance has two meanings:- a pure compound- frequently substance is considered a synonym of materialSo a solution contain a dissolved substance (solute) but colloquially also a solution can be called substance.
