A BTU is a unit of heat. If 10 BTU are transferred to 10 pounds of water, the water temperature rise will be closest to:

Explanation:
The main idea is how heat changes temperature when you know the mass and the substance’s specific heat. For water, the specific heat is 1 BTU per pound per degree Fahrenheit. That means to raise 1 pound of water by 1°F you need 1 BTU. Here, you’re applying 10 BTU to 10 pounds of water. Use the formula ΔT = Q / (m × c). With Q = 10 BTU, m = 10 lb, and c = 1 BTU/(lb·°F), you get ΔT = 10 / (10 × 1) = 1°F. So the water temperature rises about 1°F. The other options would require different amounts of energy for the given mass (0.1°F would need 1 BTU total for 10 lb, 10°F would need 100 BTU, and 100°F would need 1000 BTU).
