Properties of Substances and Processes

When it comes to the properties of substances and the processes that can change them, there are several key concepts to consider. Let's explore these concepts and identify the processes that can alter the properties of substances or lead to the formation of new substances.

Processes that Change the Properties of Substances or Lead to the Formation of New Substances:

1. Freezing - This process involves the transition of a substance from a liquid state to a solid state as a result of the removal of heat energy [[1]]. 2. Melting - The opposite of freezing, melting is the process in which a substance changes from a solid state to a liquid state due to the addition of heat energy [[2]]. 3. Evaporation - This process occurs when a liquid substance changes into a gaseous state as a result of the application of heat energy [[3]]. 4. Condensation - The reverse of evaporation, condensation is the process in which a gas changes into a liquid state due to the removal of heat energy [[4]]. 5. Combustion - Combustion is a chemical process in which a substance reacts with oxygen, typically producing heat, light, and new substances. An example of combustion is the burning of gasoline, which produces carbon dioxide and water vapor [[5]]. 6. Oxidation - Oxidation is a chemical process that involves the reaction of a substance with oxygen, resulting in the formation of new substances. An example of oxidation is the rusting of iron when it reacts with oxygen in the presence of moisture [[6]]. 7. Fermentation - Fermentation is a metabolic process in which microorganisms, such as yeast, convert sugars into alcohol and carbon dioxide. This process is commonly used in the production of alcoholic beverages and bread-making [[7]].

Processes that Do Not Change the Properties of Substances or Lead to the Formation of New Substances:

1. Mixing - Mixing refers to the process of combining two or more substances together without any chemical reaction occurring. The substances involved in mixing retain their individual properties [[8]]. 2. Dissolving - Dissolving is the process in which a solid substance (solute) disperses uniformly in a liquid substance (solvent) to form a homogeneous mixture. The properties of the solute and solvent remain unchanged in this process [[9]]. 3. Sublimation - Sublimation is the process in which a solid substance directly transitions into a gaseous state without passing through the liquid state. An example of sublimation is the conversion of solid carbon dioxide (dry ice) into carbon dioxide gas [[10]].

Please note that this is not an exhaustive list of all the processes that can change the properties of substances or lead to the formation of new substances. There are many other chemical and physical processes that can have similar effects.
