How waves carry energy but not matter and how does energy move during changes of matter?
The particles 'take part' in the wave by bumping into one another and transferring energy. This is why energy can be transferred, even though the average position of the particles doesn't change. Substances can change between the states of matter by adding or removing heat, also known as the transfer of thermal energy. Adding thermal energy causes a substance's particles to move faster and farther apart; removing thermal energy causes a substance's particles to move slower and closer together.
Dear Rk Naresh, waves are a means by which energy is transmitted through a medium or space, but they do not transfer matter. When a wave propagates, it carries energy from one location to another without physically displacing the particles of the medium. This is known as the transfer of energy without the transfer of matter.
During changes of matter, energy transfer occurs through the exchange of kinetic energy between particles. Energy is absorbed or released as the particles' motions change due to changes in temperature or other external factors. It's important to note that energy transfer is not limited to phase changes but also applies to other processes like chemical reactions, where the arrangement of atoms and molecules is altered while energy is exchanged.
