a). Define diffusion. Explain the rate of order of diffusion in solid,liquid and gase?
b). state the effect of temperature in diffusion
Answers
Answer:
Intermixing of particles of two different types of matter, on their own is called diffusion.
Diffusion in gases is very fast. This is because the particles in gases move very quickly in all directions.
Diffusion in liquids is slower than that in gases. This is because the particles in liquids move slowly as compared to the particles in gases.
Diffusion can also takes place in solids. Diffusion in solids is very, very slow process.
The rate of diffusion increases on increasing the temperature of the diffusing substance whereas it decreases when decreasing the temperature of the diffusing substance.
Answer:
The molecules of gas have more kinetic energy than liquid molecules and are smaller. ... The distance between the constituent particles in gases becomes greater than in liquids, resulting in diffusion faster in gases than in liquids. Therefore, gas particles have higher kinetic energy and travel more rapidly.
