Calculate the energy change for a pure substance over a temperature range. The following information is given for mercury at 1 atm:

boiling point = 356.6 °C

(Triangle)H vap(356.6 °C) = 295.6 J/g

melting point = -38.90 °C

(Triangle)H fus(-38.90 °C) = 11.60 J/g

specific heat gas = 0.1040 J/g °C

specific heat liquid = 0.1390 J/g °C

A 42.80 g sample of liquid mercury is initially at 48.00 °C. If the sample is heated at constant pressure (P = 1 atm), calculate the amount of
energy in LJ needed to raise the temperature of the sample to 367.50 °C.

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?
