How much sensible heat is added if the temperature of air increases from 70 to 80 F?

To determine the amount of sensible heat added when the temperature of air increases from 70 to 80 degrees Fahrenheit, one must understand that sensible heat refers to the heat exchanged by a substance that results in a temperature change without a change in phase.

The sensible heat change can be quantified by the difference in temperature. In this case, the temperature change is calculated by subtracting the initial temperature from the final temperature:

80°F - 70°F = 10°F

This result indicates that there is a 10-degree increase in temperature, which directly corresponds to the amount of sensible heat added to the air. Hence, the sensible heat added is represented precisely by this temperature change.

It is important to note that while temperature changes can be measured in degrees Fahrenheit, the significant factor here is that the increase from 70°F to 80°F translates to a straightforward calculation of heat addition in sensible terms, leading to the conclusion of 10°F as the correct amount of sensible heat added.
