Concept explainers
If the temperature of a cup of coffee decreases from
Interpretation:
The temperature change from
Concept Introduction:
The temperature can be measured in terms of degree Celsius and kelvin. Temperature is an intensive property.
The temperature change in units of Kelvin is same as the temperature change obtained in units of Celsius.
Answer to Problem 86QP
Solution:
The change in temperature from
Explanation of Solution
:
The calculation for the change in temperature from
Here,
The initial temperature is given as
