An athelet takes 20 breaths per minute at room temperature. The air inhaled in each breath is `200mL` which contains `20%` oxygen by volume, while exhaled air contains `10%` oxygen by volume. Assuming that al the oxygen consumed if used for converting glucose into `CO_(2)` and `H_92)O_((l))` , how much glucose will be burnt in the body in one hour and what is the heat produced ? `(` Room temperature `-27^(@)C` and enthalpy of combustion of glucose is `-2822.5kJ mol^(-1) at 0^(@)C)`

Answer

`29.35g,458.66kJ;`
