Diffusion of Gases: 1. The spontaneous mixing of molecules of different gases by random motion and collision until the mixture becomes homogeneous is called diffusion of gases. 2. Molecules of more than one gas are involved. 3. Molecules of lighter gases diffuse fastly. Effusion of Gases: 1. The escaping of one by one gas molecules…
Statement: “The total pressure exerted by a mixture of gases is the sum of the partial pressure of all the gases present in the mixture”. Dalton’s law of partial pressure formula/Equation: Mathematically, P= P1 + P2 + P3 – – – – – – – Where P1, P2 and P3 are the partial pressures of…
Definition: The relationship, which shows the effect of simultaneous changes in pressure and temperature on the volume of given mass of a gas is called ideal gas law or combined gas law. Mathematical Form: (General gas equation) Mathematically, it is expressed as PV = nRT This equation is derived by combining Boyle’s law, Charles’ law…
Following statement of Charles’ law helps to derive absolute zero of temperature. “At constant pressure the volume of a given mass of an ideal gas increases or decreases by 1/273 of its original volume at 0°C for every 1°C rise or fall in temperature respectively.” ABSOLUTE ZERO TEMPERATURE Definition: The temperature at which volume of…
Introduction: In 1787, Charles found a relationship between volume and temperature of gases. He announced this relationship in the form of a law known as Charles’ law: Definition: “Volume of a given mass of a gas is directly proportional to the absolute temperature at constant pressure.” Mathematical Charles Law Formula: Another Statement for Charles’ Law:…
Introduction: In 1662, Boyle found a relationship between volume and pressure of gases. He announced this relationship in the form of a law known as Boyle’s law. Statement: “At constant temperature, volume of a given mass of a gas is inversely proportional to pressure exerted on it.” OR “Product of pressure and volume of a…
