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.
A substance that cannot be separated physically is a pure substance.
"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.
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.
it is a pure substance.... not
Methane is a pure substance.
nope.

It would be a mixture of various minerals and chemicals if any were present in the water before evaporation
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.
At Boiling Point all the material evaporates leaving no residue which means it is pure. But if it leaves some residue after evaporating at boiling point then it is not pure. For example : If you take an example of pure water & Saline Water then pure water will evaporate at its boiling point leaving nothing after it. But Saline water evaporates leaves salt behind it.
