A pressure wave is a type of mechanical wave that propagates through a medium via the oscillation of particles, transferring energy without the permanent displacement of the medium itself. Commonly associated with sound waves in air, pressure waves can occur in any state of matter and are characterized by regions of compression and rarefaction.

Energy transfer is the process by which energy moves from one system or object to another, often changing form in the process. This fundamental concept is crucial for understanding various physical phenomena, from biological processes to mechanical systems and thermodynamics.

States of matter are distinct forms that different phases of matter take on, primarily influenced by temperature and pressure. The main states include solid, liquid, gas, and plasma, each with unique characteristics and transitions between them, such as melting, freezing, and vaporization.
