Answer:Hey friend this is the answer hope u will understand it quickly
Explanation: The particles can move around and mix with other particles. ... In gases the particles are much further apart than in solids or liquids. There is a lot of space in between the particles and they are constantly moving about. The particles collide with other particles and with the walls of the container.
1) Gold nanoparticles absorb and scatter light with extraordinary efficiency.
2) Their strong interaction with light occurs because the conduction electrons on the metal surface undergo a collective oscillation when they are excited by light at specific wavelengths.
