What happens to the water temperature when 10 BTU is transferred to 10 pounds of water?

When 10 BTU (British Thermal Units) is transferred to 10 pounds of water, the water temperature increases. To understand why the correct answer is that the temperature increases by 1°F, we can use the specific heat capacity of water, which is approximately 1 BTU per pound per degree Fahrenheit.

In this situation, if you transfer 10 BTU to 10 pounds of water, you can calculate the temperature change using the formula:

Temperature Change (°F) = Amount of BTUs / (Weight of Water in pounds * Specific Heat)

Substituting the values:

Temperature Change = 10 BTU / (10 pounds * 1 BTU/pound/°F) = 10 / 10 = 1°F

This calculation shows that the temperature of the water indeed increases by 1°F. The other options are either based on incorrect assumptions about the transfer of heat or misunderstandings regarding the capacity of water to absorb heat. Therefore, the correct choice is that the water temperature increases by 1°F after transferring 10 BTU of energy.
