In the past, scientists were surprised that an endothermic process like the one in this lab, could be spontaneous. Which statement correctly describes why it seems like an endothermic process should not be spontaneous? Group of answer choices All endothermic processes create order in both the system and surroundings. Endothermic processes cause heat to flow from a cold object to a hot object. A process that spontaneously takes in energy seems to be analogous to a rock rolling up a hill. Endothermic processes become so cold that molecular motion stops.
A calorimeter contains 100.0 g of water at 39.8 ºC. An 8.23 g metal object at 50.0 ºC is placed in the calorimeter. When equilibrium has been reached, the new temperature of the water and metal object is 40.0 ºC. What type of metal is the object made from (Refer to Table 1 )? (Assume that all the heat released by the metal was absorbed by the water.) Show all work with units. The answer must contain the correct units and the correct number of significant figures, please
