A - its condensation and gas particles have a higher kinetic energy
equilibrium
Heat transfers from a body with high temperature to a body with low temperature until both bodies are in the same temperature.
Answer:
When atoms are excited they emit light of certain wavelengths which correspond to different colors. Each element produces a unique set of spectral lines. Since no two elements emit the same spectral lines, elements can be identified by their line spectrum.
