An astronaut spacesuit will be equipped with a phase change material (PCM) padding that absorb the excess temperature and help maintain astronaut physiological temperatures. For this purpose, you were asked to choose a PCM that should accommodate spacesuit temperature maintained at 37 C for 1 hour at temperatures reaching 50 C with a power output of 80 W. Considering the material will be used as a padding of spacesuit fabric (make your assumptions accordingly) determine which PCM material will be the most suitable providing the properties of the chosen material and explain the reason.
