Pressure - Temperature Relationship Calculated constant, k (P.1) Data and Calculations for Temperature Pressure Relationship Pressure Temperature Temperature Calculated (kPa) (°C) (K) Constant, (P/T) 100.88 26.0 299.15 0.33122 105.13 60.1 333.25 0.31547 106.33 75.5 348.65 10.30498 108.40 83.5 35b.bs 0.30394 110.38 95.0 318.15 0.29982 30178.252 350 34 573 37071.955 138660.86 40636.97 Processing the data 1. A way to determine if a relationship is inverse or direct is to find a proportionality constant, k, from the data. If this relationship is direct, the k will be a constant fork - PT. If it is inverse, thek will be a constant for k=p. Calculate the values fork in the last two columns of the Data and Calculations table. Which relationship gave constant values? For this relationship, were all the values of k identical? If not, what is the reason for the variation? k=PIT constant values. All the values fork were not constant due to instrumental or human errors that occured in the experimental Observations 2. Based on the data that you obtained for this experiment, express in words the relationship between gas pressure and temperature, k=plta constant. The gas pressure (P) is directly Proportional to the temperature. 3. What two experimental factors were kept constant during the experiment? W Volume 8 gas and moles & gas (m) 4. Write an equation to express the relationship between pressure and temperature (K). Use the symbols P, T, and k PIT =k P = KXT. 5. Pressure is the result of the collisions of molecules with the walls of the container, which exerts a force on them. Considering your data and recognizing that the number of molecules in the flask remained fixed, what can you conclude about the molecular velocities of molecules as temperature increased? 2
