If 1 BTU is added to 1 pound of water, what is the resultant temperature increase in degrees Fahrenheit?

When you add 1 BTU (British Thermal Unit) to 1 pound of water, the resultant temperature increase is indeed 1 degree Fahrenheit. This principle stems from the definition of BTU itself, which is the amount of heat required to raise the temperature of one pound of water by 1 degree Fahrenheit.

Understanding this concept is crucial in thermodynamics and HVAC systems, as it directly relates to energy transfer and temperature regulation in fluids. By knowing that 1 BTU results in a 1 degree F increase, you can apply this knowledge to real-world scenarios involving heating systems, ensuring efficient operation and effective temperature management.
