law of partial pressures

• Princípio científico que afirma que, em uma mistura de gases que não reagem entre si, a pressão total é igual à soma das pressões parciais de cada gás individual. Também é conhecido como lei de Dalton.

A scientific principle stating that in a mixture of non-reacting gases, the total pressure exerted is equal to the sum of the partial pressures of each individual gas. Also known as Dalton's law.

   A principle in chemistry stating that the total pressure exerted by a mixture of non-reacting gases is equal to the sum of the partial pressures of each individual gas.

   Lei das pressões parciais

   • According to the law of partial pressures, the total pressure in the container is the sum of the pressures of oxygen and nitrogen.
   • The law of partial pressures helps explain how gases behave in a mixture.
   • Dalton's law of partial pressures is fundamental in understanding gas exchange in the lungs.
