Marking Scheme Lab 4: Ideal Gas Law Revised on 2006-04-27 0.5/10 1. Purpose 1.5/10 2. Theory ¾ Write down the equation of state for an ideal gas and describe each term of the equation. ¾ This equation is only valid at relatively low pressures since the equation does not take into account a significant behavior of particles occurring at higher pressures. What behavior is this equation neglecting? 4.5/10 3. Results R accepted = 0.08206 atm L / mol K 3.2 Relation between Temperature and Pressure 1.5/4.5 Graph Figure #1: Pressure “P” as a function of Temperature “T” 0.75/4.5 With Figure #1 find R (R

Discussion 4.1 Questions 4.2 Discussion of results ¾ Compare your experimental R values with ‘R accepted ’. ¾ How does “P” vary with “T”? ¾ How does “P” vary with “V”? ¾ Can we consider air as an ideal gas? -If not, why? -If so, under what condition? 4.3 Sources of error and improvements 4.4 Conclusion...
