Question

The temperature of a body rises through \[{{1}^{0}}C\]. What will be the corresponding rise in Kelvin scale?

Answer 1

Hint: The Celsius scale and Kelvin scale are measures of temperature of a body. Using proper relations between the two scales we can convert between the scales or we can find the temperature in one of the other scales according to the need.

Complete answer:
The Celsius scale is the most widely used scale of measuring temperature in our day-to-day life. This is because the range in which the scale is measured is more of our daily need. The \[{{0}^{0}}C\] of the Celsius scale is the temperature at which water freezes to ice at normal pressure conditions. Also \[{{100}^{0}}C\] is the temperature at which the water turns to steam. As a result, the Celsius scale is important to us.
It was when the absolute temperature scale was developed, we came to realise that there is a minimum attainable temperature denoted as 0K below which no temperature exists. So, the Kelvin scale became more important to the scientific community which deals with sub-zero temperatures. In order to avoid any chaos, this scale was calibrated with the Celsius scale such that their starting points only vary. The rise in 1 unit of any scale implies the rise in 1 unit by the other scale also.
The equivalent temperature magnitudes were defined as –
\[\begin{align}
  & 0K=-{{273.15}^{0}}C \\
 & \text{and,} \\
 & {{T}_{k}}=-{{273.15}^{0}}C+{{T}_{c}} \\
\end{align}\]
From this, we can conclude that \[{{1}^{0}}C\] rise implies 1K rise in the Kelvin scale also.

Note:
With the introduction of Kelvin scale, many doubts related to the temperatures and molecular vibrations were solved. At the absolute zero, the molecules will lose all its energy and there will be no molecular vibrations in them. Such a low temperature is difficult to set up.
