Water temperature refers to how hot or cold water is, measured in degrees Celsius (°C) or Fahrenheit (°F). It plays a crucial role in various natural processes, including weather patterns, aquatic life, and chemical reactions. For example, warmer water can hold less dissolved oxygen, which affects the survival of fish and other aquatic organisms. In everyday life, water temperature is important for activities like swimming, cooking, and bathing. Swimming pools often maintain a comfortable temperature for users, while cooking requires specific temperatures for food safety. Understanding water temperature helps ensure safe and enjoyable experiences in both recreational and practical settings.
