Hot liquids are substances that are heated to a temperature above room temperature, typically above 100 degrees Fahrenheit (38 degrees Celsius). Common examples include boiling water, coffee, and tea. These liquids can be used for cooking, beverages, or even in industrial processes. When handling hot liquids, it is important to exercise caution to avoid burns or scalds. The heat can cause damage to skin and tissues, so using protective gear like oven mitts or heat-resistant gloves is advisable. Always allow hot liquids to cool before consuming or handling them directly.
