Question

Pre-Laboratory Questions for Lab 10 1. The ideal gas law is an equation used for examining ideal gases. The four tenets of kinetic molecular theory define what an ideal gas is. However, no ideal gases exist in nature, only real gases do. Van der Waals' equation attempts to make corrections to real gases that do not exhibit ideal behavior. Two gases are given below that do not exhibit ideal behavior. Explain for each one why it doesn't exhibit ideal behavior. Xe (g) HO (9) (or steam) 2. Explain in your own words: how does pressure change as temperature increases for an ideal gas? Write the numerical law that describes this relationship. 3. Explain in your own words: how does volume change as pressure increases for an ideal gas? Write the numerical law that describes this relationship.

Answer 1

in 3 As Temperature increases kinetic energy of a Gas molecules increases as a result no. of collisions a made by gas molecules on the walls of the container- also increases, as a result Pressure of gas increases. (ie) T&P Gay Lussac's Law - At constant volume, Pressure of given mass of gas is directly propotional to Temperature. (e) JP &T PEKT) K = constant P = constant ② * As pressure increases , volume of given mass of gas decreases for an ideal gas. * It can be explained by Boyles Law Boyle's Law At constant Temperature, the volume of given mass of gas is inversely related to the pressure (ie) val at constant Temperature ven =) | PV = constant ongtodo lydd
