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 all the oxygen consumed if used for converting glucose into `CO_(2)` and `H_(2)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)`

Explanation

To solve the problem, we will follow these steps:

### Step 1: Calculate the volume of oxygen inhaled and exhaled per minute.
- The athlete takes 20 breaths per minute.
- Each breath contains 200 mL of air.
- The inhaled air contains 20% oxygen, while the exhaled air contains 10% oxygen.

**Calculation:**
