Which statement is false? a. The density of a gas is constant as long as its temperature remains
constant.
b. Gases can be expanded without limit.
c. Gases diffuse into each other and mix almost immediately when put into the
same container.
d. The molecular weight of a gaseous compound is a non-variable quantity.

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?
