During summer, tap water can become hotter due to prolonged exposure to ambient temperatures and heat from pipes. In contrast, water from a matka or refrigerator remains cooler, thanks to natural insulation or refrigeration.
During summers, the tap water may be hotter than the cold water from a matka (earthen pot) or a refrigerator. Explain.

In summer, tap water often becomes hotter because it is stored in pipes exposed to high ambient temperatures for extended periods. This heat transfer raises its temperature significantly. Conversely, water from a matka (earthen pot) benefits from natural cooling due to the pot’s porous structure, which allows evaporation, while water from a refrigerator is actively cooled. These factors contribute to tap water being warmer than the cooler alternatives during hot weather.
