Two of the types of ultraviolet light, uvb and uvc, are both components of sunlight. their wavelengths range from 280 to 320 nm for uvb and from 100 to 280 nm for uvc. compare the energy of microwaves, uvb, and uvc. rank from greatest to least energy per photon. to rank items as equivalent, overlap them.

Melting and boiling are endothermic processes. this means that these processes absorb energy from their surroundings in order to occur. use this information and the data you collected in the phase change gizmo to describe what happens to the temperature of water when you boil it, then explain why this result occurs.

Based on its chemical properties, identify the position of each chemical family on the periodic table.

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?
