Maize is stored in a sealed facility. The initial moisture content is 14\% (wet basis). At 20\,\degree C the respiration rate of the grain is 0.12\,g\,CO_{2}\,kg^{-1}\,day^{-1}. The respiration rate doubles for each 10\,\degree C rise (Q_{10}=2). For the first 5\,days the temperature is 25\,\degree C, after which it rises to 30\,\degree C and remains constant. Each gram of CO_{2} produced increases the moisture content by 0.5\% (wet basis). The critical moisture content for spoilage is 15\% . Assuming the moisture increase is only due to respiration, after how many days will the moisture reach the critical level? Give your answer to one decimal place.
