Part 1: Effect of temperature on time Using https://phet.colorado.edu/sims/html/gas-properties/latest/gas-properties_en.html Feichi Note: Variables to be kept constant in part 1: . Width of the container (10. nm where 1 nm = le-7 cm) . Number of particles (only 2% for both red and blue) 200 Options to be selected on the Simulation. . Select "width" Select "stopwatch" to measure time . Select "nothing"Procedure: 1. Pump blue particles first in the container. 2. Measure the pressure as soon the particles enter (the temperature would be 27C itself) 3. Start the stopwatch 4. Increase temperature every to second and record pressure immediately. 5. Record it in the table below.6. Make a graph for the particle of your choice for increase in temperature using excel - temperature (y axis) over time (x axis) +4 pressure temperature Table 1: Blue particles Time/s Temperature/ c T (k) Pressure/ kPa 0 27 300. 15 2383 40 37 310.15 +1 80 47 320. 15 + 1 120 57 3 30. 15 + 1 160 67 340.15 + 1 200 77 350!15 +1 Pressure Avg...

Answer: Insert the graph '1' LL\" 1. What effect does the increase in temperature have on pressure in this period of time for heavier particles? H 2. Why there is temperature as soon as the particles are inserted in the container? Answer: 3. Using particle theory, what would happen to the pressure if the temperature is decreased? Compare between the light and heavy particles.+ Answer4. Calculate the moles of the blue particles using the average values from Answer table 1. Assume container is a cube with each side 10 nm in length. PV = n RT P = UR T + 1 yam x slope = MR + 1 V n = V . slope + 1 RPart 2 Changing the width to measure pressure Change the number of particles to 200 ( whether you use heavy or light particles for the next Using activity ) https://phet.colorado.edu/sims/html/gas-properties/latest/gas- properties_en.html Procedure: 1. Keep temperature constant 27C = 300. 15 K 2. Change the width using the value below from the table and measure the pressure. 3. Make a graph using excel for a particle of your choice : Pressure (y axis) over width (x axis) + Table 2 blue particles Widthm Pressure/ kPa 10 + 1 20 + 1 30 40 50 50Pressure Avg.......

Where: - P = pressure - V = volume - n = moles - R = ideal gas constant . T = temperature 1. A sample of methane gas collected at a pressure of 1.28 atm and a temperature of 29.0 degrees Celsius is found to occupy a volume of 27.6 liters. How many moles of CH4CH4 gas are in the sample? +5 2. A gas that occupies a volume of 6.75 L at 89.0 atm will occupy what volume at 68.55 mm Hg if the temperature remains constant? I 3 3. Suppose that a gas originally at standard temperature and pressure undergoes a change in which its pressure is quadrupled while its temperature is cut in half. W'hat change in volume does the gas experience during this process\"? +3
