A tank holds 500 liters of water. If 235 liters are used, how much water is left if an additional 2% of the remaining water evaporates?

**A tank holds 500 liters of water. If 235 liters are used, how much water is left if an additional 2% of the remaining water evaporates?** When a 500-liter tank holds water and someone uses 235 liters, only 265 liters remain. But the real conversation here isn’t just about the numbers—it’s about evaporation, a quiet factor that affects stored water over time. Even after usage, water begins to diminish through natural evaporation, especially in warmer climates common across the U.S. **Why This Pattern Is Gaining Attention in the U.S.**
With rising temperatures and frequent heatwaves, especially in states like Texas, Arizona, and Florida, water conservation and efficient storage are increasingly relevant. Households and rural properties using large tanks for irrigation, cooling, or emergency supply are noticing how evaporation impacts available volume long after filling. The query reflects growing public interest in reliable water availability and subtle losses—something many users search for when planning storage, budgeting, or emergency readiness. **How It Actually Works**
After using 235 liters from a full 500-liter tank, 265 liters remain. A 2% evaporation loss means 2% of 265—5.3 liters—disappears naturally. The final volume is 265 minus 5.3, amounting to approximately 259.7 liters. This subtle reduction matters most when tracking usable water over time, especially during dry seasons or in off-grid setups.
