If 10 BTUs are transferred to 10 pounds of water, what will be the closest increase in water temperature?

When considering the increase in temperature of water due to the transfer of heat, it's important to apply the concept of specific heat capacity. The specific heat capacity of water is approximately 1 BTU per pound per degree Fahrenheit. This means that it takes 1 BTU to raise the temperature of 1 pound of water by 1°F.

In this case, 10 BTUs are being added to 10 pounds of water. Since each pound requires 1 BTU to raise its temperature by 1°F, 10 pounds of water will require a total of 10 BTUs to increase its temperature by 1°F. Therefore, transferring 10 BTUs to 10 pounds of water will lead to an increase in temperature of 1°F.

This understanding of specific heat capacity and how it applies to the given scenario is the basis for determining the temperature change, making the answer both accurate and grounded in the principles of thermodynamics.
