Solving the Water Pouring Problem Using Two Vessels

To solve this problem, we can use the concept of the water pouring problem, where we have two vessels with capacities of 8 liters and 5 liters. The goal is to measure 7 liters of water using these vessels.

Step 1: Fill the 8-Liter Vessel - Fill the 8-liter vessel completely from the water source.

Step 2: Pour Water from the 8-Liter Vessel to the 5-Liter Vessel - Pour water from the 8-liter vessel into the 5-liter vessel until the 5-liter vessel is full. This leaves 3 liters of water in the 8-liter vessel.

Step 3: Empty the 5-Liter Vessel - Empty the 5-liter vessel completely.

Step 4: Pour Water from the 8-Liter Vessel to the 5-Liter Vessel - Pour the remaining 3 liters of water from the 8-liter vessel into the empty 5-liter vessel.

Step 5: Fill the 8-Liter Vessel Again - Fill the 8-liter vessel completely from the water source.

Step 6: Pour Water from the 8-Liter Vessel to the 5-Liter Vessel - Pour water from the 8-liter vessel into the 5-liter vessel until the 5-liter vessel is full. This leaves 6 liters of water in the 8-liter vessel.

Step 7: Fill the 5-Liter Vessel from the 8-Liter Vessel - Fill the 5-liter vessel completely from the 8-liter vessel.

Result: - After following these steps, we have 7 liters of water in the 8-liter vessel and 5 liters of water in the 5-liter vessel, achieving the goal of measuring 7 liters of water.

This method uses a series of pouring and transferring steps to achieve the desired quantity of water.
