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…
The pressure of air that can support 760 mmHg column at sea level is called one atmosphere. OR It is a force exerted by 76 cm long column of mercury on an area of 1 cm2 at 0°C. Atmospheric Pressure at Sea Level: It is the average pressure of atmosphere at sea level. i.e.; 760…
Gases have following properties. 1. Since gases occupy all the available space, therefore, they do not have definite volume. 2. They do not have a definite shape. 3. The gases bubble through liquids and tend to rise up due to their relatively low densities. 4. Gases can diffuse and effuse. This property is negligible in…
