Question

hey i have some question if you know then please tell

1. Do all substance diffuse at the same rate? Explain with example.

2.Name the type of matter classified on the chemical basic.
​

Answer 1

Answer:

Diffusion and Effusion

Gas Diffusion and Effusion

Due to their constant, random motion, gas molecules diffuse into areas of lower concentration, and effuse through tiny openings.

LEARNING OBJECTIVES

Explain the concepts of diffusion and effusion.

KEY TAKEAWAYS

Key Points

Gaseous particles are in constant random motion.

Gaseous particles tend to undergo diffusion because they have kinetic energy.

Diffusion is faster at higher temperatures because the gas molecules have greater kinetic energy.

Effusion refers to the movement of gas particles through a small hole.

Graham’s Law states that the effusion rate of a gas is inversely proportional to the square root of the mass of its particles.

Key Terms

diffusion: movement of particles from an area of high concentration to one of low concentration

mean free path: the average distance traveled by a particle between collisions with other particles

Effusion: movement of gas molecules through a tiny hole

Diffusion

The kinetic theory describes a gas as a large number of submicroscopic particles (atoms or molecules), all of which are in constant rapid motion that has randomness arising from their many collisions with each other and with the walls of the container.

Diffusion refers to the process of particles moving from an area of high concentration to one of low concentration. The rate of this movement is a function of temperature, viscosity of the medium, and the size (mass) of the particles. Diffusion results in the gradual mixing of materials, and eventually, it forms a homogeneous mixture.

Chemical substances can be solids, liquids, gases, or plasma. Changes in temperature or pressure can cause substances to shift between the different phases of matter.
