CHE SIGNIFICA GRAHAM'S LAW IN INGLESE
La legge di Graham
La legge di Graham ", nota come legge di effusione di Graham, è stata formulata dal chimico fisico scozzese Thomas Graham nel 1848. Graham trovò sperimentalmente che il tasso di effusione di un gas è inversamente proporzionale alla radice quadrata della massa delle sue particelle. Questa formula può essere scritta come: dove: Rate1 è il tasso di effusione del primo gas. Rate2 è il tasso di effusione per il secondo gas. M1 è la massa molare del gas 1 M2 è la massa molare del gas 2. p1 è la pressione del gas 1. p2 è la pressione del gas 2. La legge di Graham prevede che il tasso di effusione di un gas è inversamente proporzionale al quadrato Radice del suo peso molecolare. Quindi, se il peso molecolare di un gas è quattro volte quello di un altro, diffonderebbe attraverso una spina porosa o scappare attraverso un piccolo pinhole in un recipiente a metà della velocità dell'altro. Una spiegazione teorica completa della legge di Graham fu fornita anni dopo dalla teoria cinetica dei gas. La legge di Graham fornisce una base per separare gli isotopi dalla diffusione - un metodo che è venuto a svolgere un ruolo cruciale nello sviluppo della bomba atomica.
definizione di Graham's law nel dizionario inglese
La definizione della legge di Graham nel dizionario è il principio secondo cui i tassi di diffusione e di effusione di un gas sono inversamente proporzionali alla radice quadrata della sua densità, proposta da Thomas Graham nel 1831.
