Ideal gas law - Wikipedia
They represent the relationship between pressure (on the vertical axis) and volume (on the horizontal axis) for an ideal gas at different temperatures: lines that are farther away from the origin (that is, lines that are nearer to the top right-hand corner of the diagram) correspond to higher temperatures.
Partial pressure - Wikipedia
The partial pressure of a gas is a measure of thermodynamic activity of the gas's molecules. Gases dissolve, diffuse, and react according to their partial pressures but not according to their concentrations in gas mixtures or liquids.
9.1 Gas Pressure - Chemistry 2e - OpenStax
The pressure of a sample of gas is measured at sea level with an open-end Hg (mercury) manometer, as shown to the right. Determine the pressure of the gas in: (a) mm Hg (b) atm (c) kPa. Solution The pressure of the gas equals the hydrostatic pressure due to a column of mercury of height 13.7 cm plus the pressure of the atmosphere at sea level.
11.4: Boyle’s Law - Pressure and Volume - Chemistry LibreTexts
2022年7月22日 · Boyle’s Law relates the pressure and volume of a gas at constant temperature and amount.
5.1: Gas Pressure, Temperature, Volume, and Chemical Amount
2023年5月2日 · Gases exert pressure, which is force per unit area. The pressure of a gas may be expressed in the SI unit of pascal or kilopascal, as well as in many other units including torr, atmosphere, and bar. Atmospheric pressure is measured using a barometer; other gas pressures can be measured using one of several types of manometers.
6.3: Relationships among Pressure, Temperature, Volume, and …
Early scientists explored the relationships among the pressure of a gas (P) and its temperature (T), volume (V), and amount (n) by holding two of the four variables constant (amount and temperature, for example), varying a third (such as pressure), and measuring the effect of the change on the fourth (in this case, volume).
9.2 Relating Pressure, Volume, Amount, and Temperature: The Ideal Gas ...
where P is the pressure of a gas, V is its volume, n is the number of moles of the gas, T is its temperature on the kelvin scale, and R is a constant called the ideal gas constant or the universal gas constant.
Gas Laws - The Physics Hypertextbook
The pressure of a gas is directly proportional to its temperature when volume is constant. Symbolically… P ∝ T (V constant) An isochoric process is one that takes place without any change in volume. This relationship doesn't really have a name, but I have heard it called the "pressure law" or (mistakenly) "Gay-Lussac's law".
Gases - Chemistry Encyclopedia - water, number, name, symbol, …
There are four intrinsic, measurable properties of a gas (or, for that matter, any substance): its pressure P , temperature T , volume (in the case of a gas, the container volume) V , and mass m , or mole number n.
Ideal Gas Constant (R) – Universal Gas Constant - Science …
2021年2月11日 · The ideal gas equation relates the pressure and volume of an ideal gas to the number of moles and temperature: PV = nRT. Here, P is pressure, V is volume, n is number of moles of an ideal gas, R is the gas constant, and T is temperature.
