How many BTUs does it take to raise 1 pound of standard air by 1 degree F?

To determine how many BTUs are required to raise 1 pound of standard air by 1 degree Fahrenheit, it’s essential to refer to the specific heat of air. Standard air, which is the air at sea level with a specific composition, has a specific heat capacity of approximately 0.24 BTUs per pound per degree Fahrenheit. This means that to increase the temperature of 1 pound of air by 1 degree Fahrenheit, you need to supply about 0.24 BTUs of energy.

This value is significant because it helps in calculations involving heating and cooling systems, as well as understanding how air behaves under different thermal conditions in HVAC applications. Knowing this specific heat can assist technicians and engineers in designing more efficient heating and cooling systems based on their requirements.
