Is it possible that Kelvin and Platinum Temperature Scale give same reading of Temperature?
Vivek098 said:What is the Temperature Scale in Platinum Resistance Thermometers?
The Kelvin temperature scale is an absolute temperature scale that is used in scientific and engineering applications. It is based on the concept of absolute zero, which is the temperature at which all molecular motion stops. On the Kelvin scale, the lowest possible temperature is 0 Kelvin (K), which is equivalent to -273.15 degrees Celsius (°C).
The Celsius scale is based on the freezing and boiling points of water, while the Kelvin scale is based on absolute zero. This means that on the Kelvin scale, there are no negative numbers as all temperatures are measured from absolute zero. Additionally, one degree Kelvin is equivalent to one degree Celsius, but the sizes of the units are different (Kelvin units are larger).
Platinum is used as the reference material for the definition of the Kelvin temperature scale. At its melting point of 1768.3 K, the resistance of platinum is precisely known, making it an ideal material for accurately measuring temperature. This led to the development of the International Temperature Scale of 1990 (ITS-90), which is based on the melting and freezing points of pure substances, including platinum.
No, the Kelvin scale is not used in everyday life as it is primarily used in scientific and engineering fields. In everyday life, temperatures are typically measured and reported in degrees Celsius or Fahrenheit.
The Kelvin scale is used in scientific experiments to accurately measure and report temperatures. This is important in experiments where precise temperature control is necessary, such as in chemical reactions or the study of materials at extreme temperatures. The Kelvin scale also allows for easier conversion between units, making it a useful tool for scientists.
