Introduction

Temperature is a fundamental physical quantity that is used to measure the thermal energy of a system. It is an essential concept in various fields, including chemistry, physics, and engineering. In this article, we will explore the concept of temperature, its measurement, and the equivalent of 0°C in Kelvin.

Temperature Scales

There are several temperature scales, including Celsius, Fahrenheit, and Kelvin. Each scale has its own set of reference points and units.

Celsius Scale: The Celsius scale is a widely used temperature scale that is based on the freezing and boiling points of water. The freezing point of water is defined as 0°C, and the boiling point is defined as 100°C.
Fahrenheit Scale: The Fahrenheit scale is another temperature scale that is based on the freezing and boiling points of water. The freezing point of water is defined as 32°F, and the boiling point is defined as 212°F.
Kelvin Scale: The Kelvin scale is an absolute temperature scale that is based on the concept of absolute zero. Absolute zero is the theoretical temperature at which all matter would have zero entropy. The Kelvin scale is defined such that 0 K is absolute zero, and the boiling point of water is defined as 373.15 K.

Converting Between Temperature Scales

Converting between temperature scales is a straightforward process. To convert a temperature from one scale to another, we can use the following conversion formulas:

Celsius to Kelvin: T(K) = T(°C) + 273.15
Fahrenheit to Celsius: T(°C) = (T(°F) - 32) × 5/9
Fahrenheit to Kelvin: T(K) = (T(°F) - 32) × 5/9 + 273.15
Celsius to Fahrenheit: T(°F) = T(°C) × 9/5 + 32
Kelvin to Celsius: T(°C) = T(K) - 273.15
Kelvin to Fahrenheit: T(°F) = (T(K) - 273.15) × 9/5 + 32

What is the Equivalent of 0°C in Kelvin?

To find the equivalent of 0°C in Kelvin, we can use the conversion formula:

T(K) = T(°C) + 273.15

Substituting T(°C) = 0, we get:

T(K) = 0 + 273.15 T(K) = 273.15 K

Therefore, the equivalent of 0°C in Kelvin is 273.15 K.

Conclusion

In conclusion, temperature is a fundamental physical quantity that is used to measure the thermal energy of a system. There are several temperature scales, including Celsius, Fahrenheit, and Kelvin. Converting between temperature scales is a straightforward process, and we can use conversion formulas to convert between the different scales. The equivalent of 0°C in Kelvin is 273.15 K.
