At what temperature does water boil at? Water boils at 100 degrees Celsius, or 212 degrees Fahrenheit. This is under normal atmospheric pressure at sea level. However, the boiling point of water can vary depending on factors such as altitude and the purity of the water.

Altitude plays a significant role in determining the boiling point of water. As altitude increases, the atmospheric pressure decreases, which in turn lowers the boiling point of water. For example, water will boil at around 95 degrees Celsius at an altitude of 2,000 meters above sea level.

Additionally, the purity of the water can also affect its boiling point. Pure water, with no impurities or dissolved substances, will have a boiling point of 100 degrees Celsius. However, water with impurities or dissolved substances will have a higher boiling point due to the presence of these substances.

It is important to note that the boiling point of water can also be influenced by external factors such as pressure cookers or other cooking methods. Pressure cookers, for example, can increase the boiling point of water by increasing the pressure inside the cooker. This allows food to cook faster at higher temperatures.

Overall, the boiling point of water is a fundamental concept in chemistry and physics. Understanding the factors that influence the boiling point of water can help in various applications, from cooking to scientific experiments. Whether you are boiling water for a cup of tea or conducting a laboratory experiment, knowing at what temperature water boils at is essential.

In conclusion, water boils at 100 degrees Celsius under normal atmospheric pressure at sea level. However, this temperature can vary depending on factors such as altitude, purity of the water, and external influences. Knowing the boiling point of water is essential for various everyday activities and scientific pursuits.
