A scientist is measuring the pressure that is exerted by each of the following gases in the atmosphere: carbon dioxide, oxygen, and nitrogen. Which term most likely describes what she is measuring is partial pressure
Explanation:
During a mix of gases, each gas supplies to the total pressure of the mixture. This supply is partial pressure. The partial pressure is the pressure of the gas if the gas held in equal capacity and temperature by itself. Partial pressure is essential in the areas of chemistry, physics, and biology. Blood levels of oxygen and carbon dioxide are defined by containing their partial pressure.
Dalton's Law of Partial Pressures states: (1) Any gas in a mix of gases uses a pressure, recognized as its partial pressure, that is equivalent to the pressure the gas would exercise if it were the unique gas present; (2) the complete pressure of the compound is the amount of the partial pressures of all the gases present.
