Boiling and melting point of water
WebNov 30, 2024 · Water boils at 100 °C (212 °F) at sea level (0 m), where pressure is higher. However, at higher altitudes, hence lower pressures, like 2000 m above sea level, water boils at 98 °C (208.4 °F). 💡 Did you know that boiling point is also affected by the amount of solute added to a solvent? As a result, the boiling point of the liquid increases. WebBoiling is the method of cooking food in boiling water or other water-based liquids such as stock or milk. [11] Simmering is gentle boiling, while in poaching the cooking liquid moves but scarcely bubbles. [12] The …
