Which is colder: -2 degrees Celsius or -8 degrees Celsius?
The Correct Answer and Explanation is:
The correct answer is -8 degrees Celsius.
To understand why, we need to examine the concept of temperature and how the Celsius scale works. The Celsius scale is based on the freezing and boiling points of water. The freezing point of water is 0°C, and the boiling point is 100°C, under standard atmospheric pressure. Temperatures below 0°C represent temperatures below the freezing point of water and are considered negative temperatures.
In this case, we are comparing -2°C and -8°C. The negative sign indicates both temperatures are below the freezing point of water. However, the number itself tells us how far below 0°C the temperature is.
- -2°C is 2 degrees below freezing, whereas
- -8°C is 8 degrees below freezing.
Therefore, -8°C is colder than -2°C because it is further below 0°C. The further below 0°C you go, the colder the temperature becomes.
To visualize it, imagine a thermometer. At 0°C, water freezes, and as the temperature drops below that, it gets colder. The lower the number, the colder the temperature. If we were to place both temperatures on the same scale, -8°C would be much lower than -2°C, indicating a much colder environment.
In practical terms, -8°C would feel significantly colder than -2°C. For instance, at -8°C, exposed skin might freeze much faster, and there could be more severe effects from prolonged exposure to the cold, such as frostbite.
In conclusion, -8°C is colder than -2°C because it represents a lower temperature on the Celsius scale, indicating a more extreme cold.
