41. Sintering under atmospheric pressure requires the use of a protective gas, quite often endothermic gas. 42. Asphyxiation is the most likely cause of death of endothermic ( warm-blooded ) prey. 43. This differs from a exothermic reaction or a endothermic reaction where the entropy is not included. 44. Any of the Tritylodonts including " Tritylodon " were warm-blooded or endothermic . 45. For instance, common endothermic building materials include calcium silicate board, concrete and gypsum wallboard. 46. Catalyzed endpoint thermometric titration of free fatty acids in tallow hydroxyl catalyzed endothermic hydrolysis of paraformaldehyde 47. The process of water-splitting is a highly endothermic process ( ?H > 0 ). 48. The actual gas mixtures are proprietary, but they usually contain ammonia and an endothermic gas. 49. Steam reforming is a good source for production of hydrogen, but the reaction is endothermic . 50. Calcination is an endothermic process and as such requires the application of heat to the calciner.
