Kelvin Scale and Celsius Scale

Introduction

The process of measuring temperature is very important for getting information related to a local region. And this can then be used for an immediate evaluation. There are many discoveries for the making of a proper temperature measurement scale. The device first introduced for the measurement of temperature was the thermoscope. Gabriel Fahrenheit produced the first thermometer in the 18th century, it is a mercury-based one. The Fahrenheit scale is the measuring scale and is still in use. The discoveries further continued for a proper scale for measuring the temperature. Later Anders Celsius introduced the Celsius scale in 1972. Lord Kelvin introduced the scale, Kelvin, in the year 1848.

What is the Kelvin Scale?

The scale developed based on some thermodynamic principles is the Kelvin scale. And the properties of the Kelvin scale do not depend on any substance. It is the SI scale of a temperature. This is represented by the symbol K. The freezing point of water on this scale of temperature is 273 Kelvin and is called absolute zero. And the boiling point of water is 373 Kelvin. Since the minimum value of temperature is 0K, a negative value of temperature is not possible in the case of a Kelvin scale. The change in thermodynamic temperatureis represented by the Kelvin scale. It is the primary unit for the calculation of a temperature in many branches of science.

Kelvin scale is developed based on thermodynamic data. Especially the Carnot cycle. Compared to other skills such as Celsius and Fahrenheit scale the Kelvin starts from zero. And is called the absolute temperature. "-273°C" is represented by the 0K. Lord Kelvin developed this scale because of the need for absolute zero. Divisions present in the Kelvin scale are Kelvin. And is based on the Celsius unit. So 1K is the same as "1°C" .

Uses of Kelvin scale

Kelvin scale is used in many fields. Some of the areas where the Kelvin scale is used are pointed out below.

• The colour temperature of light sources is measured with the help of the Kelvin scale

• The noise temperature of electronic equipment is usually measured on the Kelvin scale

• In the astronomical field, the Kelvin scale is used.

• It also includes zero as the lack of temperature

Conversion of Celsius to Kelvin

Celsius and Kelvin are two important units that can be used for measuring the hotness or coldness of a particular material. They can also be used in a way that can be converted to each other. For this, a symbol mathematical formula can be used for its conversion. The formula is,

$$\mathrm{T (K)= T (°C)+ 273.15}$$

So, the summation of over 273.15 will lead to the conversion of a temperature in a degree Celsius into temperature in Kelvin. This formula has been used in many branches of science such as physics, chemistry, and mathematics for the calculation of many important terms.

What is the Boiling Point of Water in Kelvin?

100°C. is the boiling point of water on the Celsius scale. It can be converted to the Kelvin scale by using the formula

$$\mathrm{T (K)= T (°C)+ 273.15}$$

$$\mathrm{=100+273.15=373.15K}$$

So, 373.2 K is the boiling point of water on the Kelvin scale.

What is the Freezing Point of Water in Kelvin?

"0°C" is the freezing point of water on the Celsius scale. This value can also be converted into the Kelvin scale by adding 273.15. That is,

$$\mathrm{T (K)= T (°C)+ 273.15}$$

$$\mathrm{=0+273.15=273.15K}$$

So, the freezing point of water on the Kelvin scale is 273.15K.

What is 1 Kelvin?

One Kelvin is defined as the 1/273.16, which is 3.6609×10^-3. It is the temperature of the triple point of H₂ O. One Kelvin is the basic increment present in the Kelvin scale. So Kelvin is a certain fraction of temperature.

What is Celsius Scale?

Another temperature scale is the Celsius scale. "°C" is the unit in the Celsius scale. When the Celsius scale was first introduced, the boiling point of water was represented by zero degrees Celsius and the melting point was represented by "100°C" . But currently, the range changes from "0°C to 100°C" . With a 1-degree Celsius difference there are 100 divisions in the scale. The absolute zero value in the case of a Kelvin scale is "-273°C" . So negative values of temperature are possible in the case of the Celsius scale.

Development of the Celsius Scale

The proper identification of the temperature of particular substances is very important for collecting more data. Anders Celsius first introduced the Celsius scale which was in a reverse scale that we use currently. Because the starting point of a scale is 100 and the endpoint zero. This was then reversed by many scientists Lyonnais, and Jean-Pierre Christin to the current form in which the freezing point and the boiling point of water are "0°C" and "100°C" . The Mercury-based thermometer was also developed by Lyonnais. The name Centigrade scale is also given to the Celsius scale because of the 100-degree intervals in the Celsius scale.

Conclusion

Measurement of temperature is very important for calculating the hotness of several substances. Kelvin and the Celsius scale are used for representing the temperature in a particular unit. They are different in the way that the Kelvin scale has absolute zero which means that no negative values are present in a Kelvin scale the first value is zero. But in the case of a Celsius scale, it has negative values, but its range is over 100 divisions. And can be easily employed for calculating the temperature. The value of temperature in the Kelvin scale can also be converted to degrees Celsius by using a simple mathematical equation.

FAQs

1. How is heat different from temperature?

The form of energy is characterized by the help of the term heat. While temperature measures the degree of coldness or hotness present in a substance.

2. Is space at absolute zero?

The temperature of space is not absolute zero, it is above that value. And is 2.7K. On the degree Celsius scale, the value is "-455°C" .

3. Which Scale is better between Fahrenheit and Celsius?

The Celsius scale is better than the Fahrenheit scale. And is because of the presence of 100 divisions. The freezing point and the boiling point of water are "0°C" and 100°C in the case of the Celsius scale. And it makes it more accurate than the Fahrenheit scale.

4. How to convert °F to °C?

The "°F" the scale of temperature can be converted into the °C with the help of the formula,

$$\mathrm{°C =\frac{5}{9(°F - 32)}}$$

Thus, the temperature will be obtained at the °C.

5. What are the freezing point and boiling point of water on the Fahrenheit scale?

The freezing point and the boiling point of water in Fahrenheit are 32°F "and 212°F."
