Concept explainers
If the temperature in a room increases from
Interpretation:
The change in temperature in terms of Kelvin is to be calculated.
Concept Introduction:
Kelvin is the SI unit of temperature and is termed as the absolute temperature scale which depicts the lowest possible temperature in any system that is
Celsius is the most common measuring unit for temperature. Celsius scale was defined by using freezing and boiling points of water but now, the triple point of water is introduced and the Boltzmann constant is the new basis for its definition.
Answer to Problem 124QP
Solution: The change in temperature in terms of kelvin is
Explanation of Solution
The calculation for the change in temperature from
Here,
The initial temperature is given as
Substitute
Therefore, the change in temperature
Now, the change in temperature in the Kelvin scale can be calculated as follows:
The conversion of Kelvin into degree Celsius can be carried out using the following relation:
Here,
The initial temperature
Here, the initial temperature
The final temperature
Here, the final temperature
The calculation for the change in temperature from
Here,
The initial temperature is
Substitute
Therefore, the change in temperature
Therefore, the change in temperature in units of Kelvin is the same as the temperature change in units of Celsius.
The temperature change in units of Kelvin is the same as the temperature change obtained in units of Celsius.
