CH110 Lecture Notes - Lecture 7: Ideal Gas
Document Summary
For a fixed amount of gas at a constant temperature, the gas volume is inversely proportional to the gas pressure. Note: that the constant is dependent on the amount of gas and on temperature. 0 k = -273. 15 c ( example: the temperature at which molecular motion ceases). Kelvin temperature and celsius temperature are related by: The volume of a fixed amount of gas at constant pressure is directly proportional to the kelvin (absolute) temperature. Note: the value of the constant depends on the amount of a gas and the pressure. The relationship is linear for both the celsius and kelvin scales, but volume is directly proportional only to the absolute (kelvin) scale. Avogadro"s law: at a fixed temperature and pressure, the volume of gas is directly proportional to the amount of gas. P n( where n is the number of moles) or v=(constant)(n) The ideal gas equation normally takes the form:
