Question

At absolute zero, how would you maintain temperature? Explain using necessary equations, figures, and/or diagrams.

Explain whether the number of binding sites will increase/decrease as a function of enthalpy or entropy. How is this important in medicinal chemistry or how a drug would function in vivo/vitro?

I am inclined to say it is a function of entropy because it correlates to concentrations?

You are working hard on homework and your brain operates at 150 J/s. You eat candy for a supply of glucose to sustain your metabolic rate for 1 hour. How much glucose (in g) must you consume?

Explanation / Answer

Ans 1. The absolute temperature is measured in kelvin where 0 kelvin is the lowest possible temperature. At absolute 0 the motion of all the gas particles comes to 0.

To maintain the temperature at 0 kelvin , laser cooling is done. In laser cooling, the atoms scatter light . The absorption of incoming laser photon by the atoms and then reemission of photons in different direction. As The scattered photon has slight higher energy than the emitted photon , total energy is conserved. And this difference in photon energy is extracted from the atomic motion , and the atom slows down. This way atoms loose energy and temperature drops to absolute 0.

Cooling can also be done by removal of the most energetic atoms from the system. It decreases the average energy and the temperature of remaining molecules thus maintaining an absolute temperature of the system.
