Introduction
Water is a vital component of our daily lives, and its properties have been extensively studied in various fields, including chemistry, physics, and biology. One of the fundamental properties of water is its boiling point, which is the temperature at which it changes state from a liquid to a gas. In this article, we will delve into the concept of boiling point, explore the factors that influence it, and provide an answer to the question: at what temperature does water begin to boil?
What is the Boiling Point of Water?
The boiling point of water is the temperature at which it boils, or turns into vapor. This occurs when the molecules of water gain enough energy to break free from the surface tension of the liquid and turn into gas. The boiling point of water is a critical parameter in various applications, including cooking, industrial processes, and scientific research.
Factors that Influence the Boiling Point of Water
Several factors can influence the boiling point of water, including:
- Atmospheric Pressure: The boiling point of water is affected by the atmospheric pressure. At higher altitudes, the atmospheric pressure is lower, which results in a lower boiling point.
- Impurities: The presence of impurities in water can affect its boiling point. For example, the boiling point of seawater is higher than that of pure water due to the presence of dissolved salts.
- Temperature: The boiling point of water is also affected by the temperature of the surrounding environment. For example, the boiling point of water is lower at higher temperatures.
The Correct Answer: 100 Degrees Celsius (212° F)
Based on the factors mentioned above, the correct answer to the question is:
- D. 100 degrees Celsius (212° F)
This is the standard boiling point of water at sea level, which is widely accepted by scientists and engineers. However, it's essential to note that the boiling point of water can vary depending on the specific conditions, such as altitude and impurities.
Why is the Boiling Point of Water Important?
The boiling point of water is crucial in various applications, including:
