The relationship between pressure and volume, when moles and temperature of a gas are held constant, is: pv = k. we could say then, that:

if the volume of the gas is doubled, the pressure also doubles.
if the volume of a gas is halved, the pressure is doubled.
if the volume of gas is doubled, the pressure is unaffected.
if the volume of a gas is halved, the pressure is tripled.

When a comet collides with earth, it adds material to our planet and causes great damage. therefore, a collision like this is a a. destructive force b. constructive force c. geologic process and event d. constructive and destructive force

What is the lowest number energy level where a d sublevel is found

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?
