Auniform steel plate has an area of 0.819 m2. when subjected to a temperature difference between its sides, a heat current* of 31700 w is found to flow through it. what is the temperature gradient? what is the temperature difference when the plate is 0.0475 m thick? the thermal conductivity of steel is 50.2 w/(m·k).

The answer is water molecules are split.cellular respiration and photosynthesis are complement  reactions to each other. these are reverse reactions. in cellular respiration glucose and oxygen yield water and carbon dioxide. so, when respiration begins,  glucose molecules are split. in the opposite reaction - in photosynthesis, carbon dioxide and water yield glucose and oxygen. thus,  when respiration begins, water molecules are split.
