Gas Laws of Boyle, Charles, & Avogadro exam Already Passed!!

3 gas laws - Boyle's Law, Charles's Law, & Avogadro's Law Boyle's Law - the volume of a given sample of gas at constant temperature varies inversely with the pressure. PV = k, k is a constant for a given sample of air at a specific temperature. (to predict the new volume of a gas when the pressure is changed (at constant temperature), or vice versa, use P1V1 = P2V2) relationship between pressure and volume - there is an inverse relationship between pressure and volume; V = k/P = k(1/P) (straight line) Is PV always constant? - No, measurements at higher pressures reveal that PV is not constant but varies as the pressure is varied. ideal gas - A gas that strictly obeys Boyle's law relationship between the Kelvin and Celsius scales - K = degrees C + 273 Charles's law - the volume of a given sample of gas at constant pressure is directly proportional to the temperature in kelvins. V = bT, where T is in kelvins and b is a proportionality constant. (To find unknowns, use V1/T1 = V2/T2) 0 K is called ________. - absolute zero Avogadro's law - equal volumes of gases at the same temperature and pressure contain the same number of "particles." Avogadro's law stated mathematically - V = an, where V is the volume of the gas, n is the number of moles of gas particles, and a is a proportionality constant. (To find unknowns, use V1/n1 = V2/n2)
