The ammonia molecule nh3 has a dipole moment of 5.0 x 10^-30cm. ammonia molecules in the gas phase are placed in a uniform electric field e with magnitude 1.6×10^6 n/c. a) what is the change in electric potential energy when the dipole moment of a molecule changes its orientation with respect to e from parallel to perpendicular? express your answer using two significant figures.
b) at what absolute temperature t is the average translational kinetic energy 3/2kt 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.

Isobars are lines of constant or equal pressure on a weather map. they can be used to find areas of low or high pressure over a broad area, and they can tell us how intense the system may be. on weather maps, you may have noticed areas that have a large l or h over a region with lines circling around them. the l stands for low pressure and h stands for high pressure. the lines circling them are isobars. check out the pressure system and isobars over georgia and florida. what is the present weather in this area ? a) clear and sunny b) cold and cloudy c) changing weather d) lots of precipitation
