Parts per million-ppm-is commonly used as a dimensionless measure of small levels(concentrations) of pollutants in air, water, body fluids, etc. Parts per million is the molar mass, volume or mass ratio between the pollutant component and the solution.... In the metric system ppm for mass can be expressed in terms of milligram versus kg where 1 mg/kg=1 part per million. 3, record 1, English, - part%20per%20million

Partie par million (ppm). C'est un quotient sans dimension représentant un rapport de 10-6 (1 pour 1 million). Ce rapport peut s'appliquer par exemple à des masses ou à des volumes. Ainsi, quand on parle d'un contenu de 400 ppm (ou plus précisément ppmv [partie par million en volume]) de CO2 dans l'atmosphère, cela signifie qu'un litre d'air contient en moyenne 0,4 ml de dioxyde de carbone. 4, record 1, French, - partie%20par%20million

Grasas y Aceites. Se refiere a los compuestos derivados del petróleo que sólo son solubles en hexano y completamente insolubles en el agua. La norma de la OMS marca 1 ppm (1 parte por millón, esto es un miligramo por litro) de grasas y aceites, sin embargo, en México la norma es de 65 ppm. 3, record 1, Spanish, - parte%20por%20mill%C3%B3n

En general, la concentración de monóxido de carbono acompaña los cambios de densidad del tránsito que se suceden a lo lorgo del día. El descanso nocturno es suficiente para borrar la memoria de la contaminación registrada el día anterior. Cada día comienza entonces con bajos niveles de concentración, para llegar a niveles cercanos a la alarma (9ppm - partes por millón - como promedio de 8 horas). 4, record 1, Spanish, - parte%20por%20mill%C3%B3n

Molar quantity is often convenient to express an extensive quantity(e. g., volume, enthalpy, heat capacity, etc.) as the actual value divided by amount of substance(number of moles). 2, record 2, English, - extensive%20quantity
Record number: 2, Textual support number: 2 CONT
Extensive variables are proportional to the size of the system. Intensive variables do not depend on the size of the system. Extensive variables: volume, mass, energy. Intensive variables: pressure, temperature, density. If we divide an extensive quantity by the number of moles (or number of particles), we obtain an intensive quantity. 3, record 2, English, - extensive%20quantity

Il existe une différence très nette entre la chaleur et la température; la chaleur est une forme de l'énergie tandis que la température n'est qu'un facteur de cette forme d'énergie; en fait d'une façon plus rigoureuse la chaleur est le produit de la température, grandeur intensive par une grandeur extensive, l'entropie. 1, record 2, French, - grandeur%20extensive
