What is the temperature difference in degrees between the freezing point and boiling point of water on the Centigrade scale at sea level?
Correct Answer:
100
Explanation:
The correct answer is based on the temperature difference between the freezing point and the boiling point of water, which is a fundamental concept in thermodynamics. On the Centigrade (Celsius) scale, the freezing point of water is defined as 0 degrees, while the boiling point is defined as 100 degrees at sea level. To determine the temperature difference, you simply subtract the freezing point from the boiling point: 100 degrees (boiling point) - 0 degrees (freezing point) = 100 degrees. This 100-degree difference is essential for understanding temperature scales and is commonly used in various scientific and everyday applications. The significance of this range is also foundational knowledge in fields such as meteorology and environmental science.
