Henry's law

Examples of Henry's law in the following topics:

• Henry's Law

  • Henry's law states that the amount of a gas that dissolves in a liquid is directly proportional to the partial pressure of that gas.
  • An everyday example of Henry's law is given by carbonated soft drinks.
  • Henry's law can be put into mathematical terms (at constant temperature):
  • The main application of Henry's law in respiratory physiology is to predict how gasses will dissolve in the alveoli and bloodstream during gas exchange.
  • Explain the way in which Henry's law relates to gas exchange in the respiratory system

• Solubility and Pressure

  • This effect can be mathematically described using an equation called Henry's law.
  • Henry's law only works if the molecules are at equilibrium and if the same molecules are present throughout the solution.
  • Henry's law does not apply to gases at extremely high pressures.
  • Henry's law does not apply if there is a chemical reaction between the solute and the solvent.
  • For example, HCl (g) reacts with water in the dissociation reaction and affects solubility, so Henry's law cannot be used in this instance.

• Basic Principles of Gas Exchange

  • The purpose of respiration is to perform gas exchange, a process that involves ventilation and perfusion and that relies on the laws of partial pressure.
  • In addition to Boyle’s law, several other gas laws help to describe the behavior of gases.
  • Dalton’s law describes the behavior of nonreactive gases in a gaseous mixture and states that a specific gas type in a mixture exerts its own pressure; thus, the total pressure exerted by a mixture of gases is the sum of the partial pressures of the gases in the mixture.
  • Henry’s law describes the behavior of gases when they come into contact with a liquid, such as blood.
  • Henry’s law states that the concentration of gas in a liquid is directly proportional to the solubility and partial pressure of that gas.

• External Respiration

  • Based on Henry's law, the greater solubility of carbon dioxide in blood compared to oxygen means that diffusion will still occur very rapidly despite the lower partial pressure gradient.

• The Anglican Church

  • Indeed, this part of Henry's reign saw the trial for heresy of Protestants as well as Roman Catholics.
  • From 1553, under the reign of Henry's Roman Catholic daughter, Mary I, the Reformation legislation was repealed and Mary sought to achieve the reunion with Rome.
  • Her first Act of Parliament was to retroactively validate Henry's marriage to her mother and so legitimise her claim to the throne.
  • The medieval heresy laws were restored and 283 Protestants were burnt at the stake for heresy.
  • The role played by various personalities at Henry's court, and the manner in which the King's own preferences shaped the doctrines of the Church of England, are considered.

• Liberty and Property

  • The resolves claimed that, in accordance with long established British law, Virginia was subject to taxation only by a parliamentary assembly to which Virginians themselves elected representatives.
  • Rothermel's "Patrick Henry Before the Virginia House of Burgesses", a painting of Patrick Henry's "If this be treason, make the most of it!

• The Magna Carta

  • The Magna Carta was the first document imposed upon a King of England to limit his powers by law and protect civil rights.
  • Robert, who invaded in 1101, disputed Henry's control of England.
  • When Richard died, his brother John – Henry’s fifth and only surviving son – took the throne
  • The charter is widely known throughout the English speaking world as having influenced common and constitutional law, as well as political representation and the development of parliament.
  • The text's association with ideals of democracy, limitation of power, equality and freedom under law led to the rule of constitutional law in England and beyond.

• Powers of the Assemblies

  • In 1764, desiring revenue from its North American colonies, Parliament passed the first law specifically aimed at raising colonial money for the Crown.
  • These laws angered many American colonists who responded with organized protests.
  • Rothermel's "Patrick Henry Before the Virginia House of Burgesses", a painting of Henry's "If this be treason, make the most of it!

• Romanesque Sculpture: Tomb of Rudolf of Swabia

  • He died as a result of battle wounds as his faction met and defeated Henry's in the Battle of Elster.

• Emerson and Thoreau

  • He was a lifelong abolitionist, delivering lectures that attacked the Fugitive Slave Law while praising the writings of Wendell Phillips and defending abolitionist John Brown.
