A fórmula barométrica como instrumento de ensino em Química The barometric formula as resource for teaching Chemistry

Abstract

The barometric equation is revisited. Restrictions imposed for its derivation are investigated. Results are discussed and related to simple themes of ordinary life. The theoretical models fit to experimental data. Correction for temperature effect improves the fitting in comparison to the barometric formula. The scope for application of the model is discussed.
