21.52 The ammonia molecule (NH3) has a dipole moment of 5,0 x 10-30C.m. Ammonia molecules in the gas phase are placed in a uniform electric field with magnitude 1.6 X 100 N/C (a) What is the change in electric potential energy when the dipole moment of a mol- ecule changes its orientation with respect to E from parallel to perpen- dicular? (b) At what absolute temperature T is the average translational kinetic energy kt of a molecule equal to the change in potential energy calculated in part (a)? (Note: Above this temperature, thermal agitation prevents the dipoles from aligning with the electric field.)
