How Do You Spell GRAHAM'S LAW?

Pronunciation: [ɡɹˈe͡ɪəmz lˈɔː] (IPA)

Graham's law refers to the diffusion rate of two different gases at the same temperature and pressure. The spelling of the word "Graham's" is pronounced as /ɡræmz/, using the IPA phonetic transcription. The first letter "G" is pronounced as a voiced velar stop, followed by the sound of "r" which is pronounced as an alveolar trill. The letter "a" is pronounced as a short vowel sound, followed by a voiced velar fricative "mz." Overall, the correct spelling and pronunciation of the word "Graham's law" is imperative for those studying gas behavior and diffusion.

GRAHAM'S LAW Meaning and Definition

  1. Graham's law, named after Scottish chemist Thomas Graham, refers to the principle and mathematical relationship that describes the diffusion or effusion rates of two different gases. The law states that the rate of diffusion or effusion of a gas is inversely proportional to the square root of its molar mass.

    In simpler terms, Graham's law states that lighter gases diffuse or effuse more rapidly than heavier gases under the same conditions of temperature and pressure. This is because the lighter gas molecules have higher average velocities and kinetic energies, allowing them to spread out and mix with the surrounding particles more quickly.

    Graham's law can be mathematically expressed as:

    Rate of Diffusion/Effusion A = √(Molar Mass of B / Molar Mass of A)

    Here, the rate of diffusion or effusion of gas A is determined by dividing the square root of the molar mass of gas B by the square root of the molar mass of gas A.

    This law is primarily applicable to gases at low pressures and high temperatures, where the behavior of gases approaches that of an ideal gas. It finds important applications in various fields, such as in the study of gas flow, the separation and purification of gases, and in the determination of molar masses of unknown substances using effusion techniques.

    Overall, Graham's law serves as a valuable tool for understanding and predicting the behavior of gases based on their molar masses.

  2. The relative rapidity of diffusion of two gases varies inversely as the square root of their densities.

Etymology of GRAHAM'S LAW

The term "Graham's law" is named after the Scottish chemist Thomas Graham, who was born in 1805 and died in 1869. He made significant contributions to the study of gases, particularly in the area of diffusion. Graham's law, formulated by him, describes the relationship between the rates of effusion or diffusion of two different gases. His work contributed to the understanding of the movement and behavior of gases, leading to the development of the kinetic theory of gases.
