Convert (-10 degrees Celsius) to Fahrenheit scale and Kelvin scale: -14°F, 263 K
The Correct Answer and Explanation is:
To convert from Celsius to Fahrenheit, the formula used is:F=95×C+32F = \frac{9}{5} \times C + 32F=59×C+32
Where C is the temperature in Celsius and F is the temperature in Fahrenheit. For -10°C:F=95×(−10)+32=−18+32=14°FF = \frac{9}{5} \times (-10) + 32 = -18 + 32 = 14°FF=59×(−10)+32=−18+32=14°F
So, -10°C is equal to 14°F on the Fahrenheit scale.
To convert from Celsius to Kelvin, the formula is:K=C+273.15K = C + 273.15K=C+273.15
Where K is the temperature in Kelvin. For -10°C:K=−10+273.15=263.15 KK = -10 + 273.15 = 263.15 \, KK=−10+273.15=263.15K
So, -10°C is equal to approximately 263.15 K on the Kelvin scale.
Explanation:
The Celsius scale and the Fahrenheit scale have different zero points and increments. The Celsius scale is based on the freezing point of water (0°C) and the boiling point (100°C), whereas the Fahrenheit scale sets the freezing point of water at 32°F and the boiling point at 212°F. This makes the Fahrenheit scale more sensitive to temperature variations within the typical range for weather. The formula for converting Celsius to Fahrenheit takes this difference into account, multiplying the Celsius temperature by 9/5 and then adding 32 to shift the scale.
On the other hand, the Kelvin scale is an absolute temperature scale. It starts at 0 K, which is absolute zero—the lowest possible temperature where atoms have minimum energy. It is primarily used in scientific contexts, such as thermodynamics. To convert from Celsius to Kelvin, we simply add 273.15 to the Celsius temperature because the two scales have the same size increments. For example, a temperature of -10°C means the temperature is 10 degrees below the freezing point of water in Celsius, and when converted to Kelvin, it reflects how much energy is available in the system relative to absolute zero.
In everyday life, Celsius is commonly used in most parts of the world, while Fahrenheit is primarily used in the United States. Kelvin is mostly used in scientific fields where precise temperature measurements are necessary.
