Diffusion vs Effusion:
Diffusion: The process of spontaneous and uniform spreading of solid, liquid, and gaseous substances in a medium is called diffusion.
Effusion: The process of rapid release of gas from high pressure to low pressure through a narrow orifice is called an effusion.
Diffusion: Diffusion is a time-consuming process.
Effusion: A very short time process due to its high speed.
Diffusion: In diffusion, the pressure difference is very less or negligible.
Effusion: The pressure difference in discharge is very high.
Diffusion: In diffusion, the particles spread slowly, so no sound is produced.
Effusion: In most cases, the sound is produced by excrement.
