Physical weathering is the process by which rocks and minerals break down into smaller pieces without changing their chemical composition. This occurs due to various environmental factors, such as temperature fluctuations, freeze-thaw cycles, abrasion from wind or water, and the expansion and contraction of materials. Physical weathering plays a crucial role in soil formation and landscape evolution by fragmenting rock materials, making them more susceptible to other weathering processes.
Irreversible chemical change.
physical because water is H2O and ice is H2O also
In distillation, two physical changes involved are evaporation (liquid turning into vapor due to heat) and condensation (vapor turning into liquid when cooled). The process separates components based on their different boiling points.
Melting point is a physical property of a substance, as it refers to the temperature at which a solid becomes a liquid. This transformation does not alter the chemical composition of the substance; it remains the same material before and after melting. Therefore, melting point is used to characterize and identify substances based on their physical behavior.
Frying chicken involves both physical and chemical changes. The physical change occurs as the chicken cooks and changes color and texture due to the application of heat. The chemical change happens as the proteins and sugars in the chicken undergo reactions that result in browning and flavor development.
