spherical and elastic particles. Although an ideal gas is a theoretical model and so cannot exist in practice‚ most gases behave fairly similarly to an ideal gas. Gases behave more like an ideal gas when they are at a higher temperature and lower pressure‚ as the potential energy of the intermolecular forces becomes negligible compared to the kinetic energy of the gas. Butane gas does follow the ideal gas law fairly well‚ as it is non-polar and hence has

On a microscopic level‚ the molecules (or atoms) in a gas are separated by large distances and are in constant‚ random motion. When dealing with gases‚ the Ideal Gas Law equation is the most famous equation used to relate all the factors in dealing and solving the problem. The four factors or variables for gas are: pressure (P)‚ volume (V)‚ number of mole of gas

the Boyle’s law (pressure-volume law) indicates that the volume of a certain amount of gas given held at a constant temperature differentiates inversely with the applied pressure when there are constant temperature and mass. Equations: PV=C. When pressure goes up‚ volume goes down (derived from the equation above): P1V1 = P2V2 = P3V3. Furthermore‚ this particular equation dictates that the product of the initial volume and pressure is equal to the product of the volume and pressure after a change under

transmission of fluid-pressure is a principle in fluid mechanics that states that pressure exerted anywhere in a confined incompressible fluid is transmitted equally in all directions throughout the fluid such that the pressure ratio (initial difference) remains the same.[1] The law was established by French mathematician Blaise Pascal.[2] Contents [hide] 1 Definition 2 Explanation 3 Applications 4 See also 5 References Definition[edit source | editbeta] Pressure in water and air.
