Question

Question 1 IT researchers have successfully cooled sodium potassium (NaK) molecules to a temperature of 500 nanokelvin. Figure 1. Ultracold Molecules water droplets g, | a) On the Energy Level Diagram (above) indicate where you would expect the relative energy level of the ultracold molecules to be. The energy level of pure water droplets has been placed as a reference. lover tan the wate dropet ene b) In a complete paragraph, defend your prediction. the lower e hempembve is tme slever tme ndecule 1s Freez.ng nolecneS ciais move with the ↑ het +ne.no lec.Aes c) Assuming, these ultracold molecules have an ave. kinetic energy 4.99 x 10-30 J, determine the average velocity (in cm/s) of NaK at this temperature.
