Gce Model Questions Vol1 2025 Agricultural Science Question 36
Practice objective / multiple choice question 36 from the 2025 Gce Model Questions Vol1 Agricultural Science examination.
A batch of maize kernels is stored in a hermetic bag at (25\,^{\circ}\text{C}\). The initial moisture content is (14\%\) (wet basis). The bag loses moisture at a constant rate of (0.5\%\) of the kernel mass per day until the moisture content reaches (12\%\). The respiration rate of the kernels is (0.02\,\text{g\,CO}_{2}\,\text{kg}^{-1}\,\text{h}^{-1}\) for each percent of moisture above (13\%\). Assuming the moisture content decreases linearly as described, calculate (a) the number of days required for the moisture content to fall to (12\%\), and (b) the total amount of CO\(_2\) (in g per kg of kernels) produced during this period.
