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) ...

Chemistry 130 Arizona College of Nursing Midterm Questions with Verified Solutions What is the atomic number of an element, and why is it important? The atomic number is the number of protons in an atom’s nucleus and determines the element's identity and position on the periodic table. How does an ionic bond form between atoms?
