Solution:-
Variable temperature NMR is used to study kinetics of molecular conformation because at low temperature the molecule can be freezed to its particular conformational structure. In this case spin-relaxation time constant is high enough to differentiate between two similar proton. By lowering temperature, we are lowering motion of the molecule.
But, in case of UV spectroscopy, We are giving energy in form of ultraviolet light to excite the molecule. In this way we are encreasing the motion of molecule. Thus, time constant to change one conformation from other is low enough to differentiate between them.

It has been proposed that the ideal temperature for producing a coffee is 90°C. However, this is too hot to enjoy the beverage. After completing the week 5 workshop content, it is up to you to mathematically model how a coffee cup's temperature varies over time 1. Consider a hot cup of coffee. The temperature in the coffee cup will decrease at a rate proportional to the difference in the current tem- perature and the ambient temperature. Based on this...
