Henry's law

1 7.1
More gas dissolves in a liquid when gas pressure over it is higher at the same temperature
  • noun
  • /ˈhɛnriz lɔ/
  • Specialized
: ley de Henry
  • From Wiki: "Henry's law is used to quantify the solubility of gases in solvents.

Examples

  • In practical applications, Henry's law helps scientists understand how carbon dioxide is absorbed in ocean water under different pressures.

  • Henry's law means that there will be a standard ratio of atmospheric CO2 to dissolved CO2 in the oceans, dependent on vapor pressure and temperature.

  • Henry's law has since been shown to apply to a wide range of dilute solutions, not merely those of gases.

  • According to Henry's law, the amount of gas that dissolves in a liquid increases with the pressure of the gas above it.

  • Henry's law states that at a constant temperature, more gas will dissolve in a liquid if the pressure is increased.

Morphology

Henry's + law

The structure "Henry's law" is an eponymous scientific label: knowing 'law' signals a general principle and knowing that 'Henry' is a name allows learners to infer this is a law named after Henry. However, the specific content (gas solubility proportional to pressure) cannot be derived from the constituents, so the full meaning is not predictable from the parts alone.

Etymology

Henry's law is named after the chemist William Henry, who noticed that when you press more on a gas, more of it goes into a liquid. So the name reminds us that higher pressure forces more gas to 'dissolve' in a liquid.
