Using gas pump handle, add some molecules to into the chamber. In the readied calculator ( "Edit", record as L1 the number of heavy molecules as shown on the right-hand "heavy species" readout. Once the particles are distributed evenly, raise or lower the temperature to 300 K. Like volume, it will remain constant throughout the experiment. If not, heat or cool the sample with the heat control until it is at the constant 300 K. Record the pressure in L2 , in atmospheres. Add more particles and record number of particles and pressure over a wide range of pressures. Think about (0 molecules, 0 atmospheres and decide whether you should include that point, too.

Take the steps to create and view the data graph. Write the relationship you see. Do a linear regression and complete the following equation.

pressure, in atom = "a" * number of molecules + "b"

What are the units of the slope "a"? What are the units of "b"?

Using your regression equation, predict the pressure of the gas when the number of heavy molecules is 500.

Check your result with the simulation. Comment on the reliability of your interpolation or extrapolation based on the other measurements.

The ozone molecule o3 has a permanent dipole moment of 1.8×10−30 cm. although the molecule is very slightly bent-which is why it has a dipole moment-it can be modeled as a uniform rod of length 2.5×10−10 m with the dipole moment perpendicular to the axis of the rod. suppose an ozone molecule is in a 8000 n/c uniform electric field. in equilibrium, the dipole moment is aligned with the electric field. but if the molecule is rotated by a small angle and released, it will oscillate back and forth in simple harmonic motion.what is the frequency f of oscillation?
