For a fixed mass of an ideal gas kept at a fixed temperature, pressure and volume are inversely proportional. [2] Boyle's law is a gas law, stating that the pressure and volume of a gas have an inverse relationship. If volume increases, then pressure decreases and vice versa, when the temperature is held constant. Therefore, when the volume is ...
This pressure is balanced by a simultaneous electrostatic force acting on the charges, and hence on the particle itself. The force has been coined the electrodipping force by Kralchevsky et al. - it dips the particle in one of the liquids. According to Nikolaides, the electrostatic force engenders a long range capillary attraction.
That is 8 times , the volume of each particle of radius / , but there are 2 particles which gives 4 times the volume per particle. The total excluded volume is then = ; that is, 4 times the volume of all the particles. Van der Waals and his contemporaries used an alternative, but equivalent, analysis based on the mean free ...
In ecology, pressure-volume curves describe the relationship between total water potential (Ψt) and relative water content (R) of living organisms. These values are widely used in research on plant-water relations and provide valuable information on the turgor, osmotic and elastic properties of plant tissues. [1] [2] [3] [4]
A meniscus as seen in a burette of colored water. '20.00 mL' is the correct depth measurement. When reading a depth scale on the side of an instrument filled with liquid, such as a water level device , the meniscus must be taken into account in order to obtain an accurate measurement.
The volume available for small spheres is the difference between the total volume of the system and the excluded volume. To determine the available volume for small spheres, there are two distinguishable cases: first, the separation of the large spheres is big enough so small spheres can penetrate in between them; second, the large spheres are ...
Once it fully sinks to the floor of the fluid or rises to the surface and settles, Archimedes principle can be applied alone. For a floating object, only the submerged volume displaces water. For a sunken object, the entire volume displaces water, and there will be an additional force of reaction from the solid floor.
2 volumes of hydrogen + 1 volume of oxygen = 2 volume of gaseous water. could also be expressed as 2 molecules of hydrogen + 1 molecule of oxygen = 2 molecule of water. The law of combining volumes of gases was announced publicly by Joseph Louis Gay-Lussac on the last day of 1808, and published in 1809.
