The ammonia molecule (NH₂) 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 1.2x10° N/C. Part A What is the change in electric potential energy when the dipole moment of a molecule changes its orientation with respect to from parallel to perpendicular? Express your answer using two significant figures. ΑΣΦ AU = Submit Part B T= Submit Request Answer Provide Feedback 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.) Express your answer using two significant figures. |VD ΑΣΦ P ? Request Answer J X ?
