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.
Pouring water of weight w down the tube will eventually raise the heavy weight. Balance of forces leads to the equation =. Glazebrook says, "By making the area of the board considerable and that of the tube small, a large weight W can be supported by a small weight w of water. This fact is sometimes described as the hydrostatic paradox."
One way to write the van der Waals equation is: [6] [7] [8] =, where is pressure, is the universal gas constant, is temperature, is molar volume, and and are experimentally determinable, substance-specific constants.
Therefore, the kinetic energy per kelvin of one mole of monatomic ideal gas (D = 3) is = =, where is the Avogadro constant, and R is the ideal gas constant. Thus, the ratio of the kinetic energy to the absolute temperature of an ideal monatomic gas can be calculated easily:

If your scale says your weight went up overnight, you might wonder: Can you gain weight in one day? Experts give 11 reasons you seemed to gain weight overnight.
Thus water behaves as though it is an ideal gas that is already under about 20,000 atmospheres (2 GPa) pressure, and explains why water is commonly assumed to be incompressible: when the external pressure changes from 1 atmosphere to 2 atmospheres (100 kPa to 200 kPa), the water behaves as an ideal gas would when changing from 20,001 to 20,002 ...
Similarly, to get an improved salt surface area, use smaller salt. “If you have two 1-pound bags of salt, but one bag has big crystals and the other has small crystals, the smaller crystals will ...
