For example, if people mix 2 or more solids in a solution, it can form a different element, such as combining melting copper, and zinc, creating brass. If people wanted to do this with water, try mixing alcohol with it, mixing alcohol and water is miscible (able to be mixed with), however oil isn’t, using alcohol is one way to melt ice.
Once using alcohol to melt ice, it dissolves into a solvent (a substance that dissolves into another liquid). Water, being the most known solvent and it turns into several different solutions. Sometimes a solvent can turn into a solid or gas, such as the universal solvent.
Combining gases into certain objects is also a thing, not just with gas, but also water, this causes a chemical reaction (when two or more elements interact and cause changes with at least one element involved). There are four types of chemical reactions: synthesis, decomposition, single and double displacement, in each type of solid, liquid, or gas. An example of double-displacement is combining ice, and salt, into water, which is the process of melting, something people are trying to figure how fast to melt at this
