Air at 20℃ and 1 atm flows over a long cylinder at 1 m/s. the cylinder has a diameter of 10mm and its initial temperature is 134℃. if the density, specific heat, and conductivity of the cylinder are 7832 kg/m3 , 549 j/kg. k, and 49.2 w/m. k, respectively, calculate the temperature at the center of the cylinder after 100 seconds.

Ibelieve the answer is b

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.
