What amount of Btu is required to raise the temperature of 1 pound of water from 32F to 212F?

• A. 150 Btu
• B. 180 Btu
• C. 212 Btu
• D. 250 Btu

Answer: (B)

To determine the amount of Btu required to raise the temperature of 1 pound of water from 32°F to 212°F, it is essential to understand the basics of specific heat and temperature change. The specific heat capacity of water is approximately 1 Btu per pound per degree Fahrenheit. The temperature difference from 32°F to 212°F is 212°F - 32°F = 180°F. Since it takes 1 Btu to raise the temperature of 1 pound of water by 1°F, raising the temperature by 180°F will require 180 Btu in total. This calculation aligns with the definition of Btu and specific heat, confirming that raising the temperature of 1 pound of water by 180°F necessitates 180 Btu. Hence, the correct amount of Btu required is indeed 180 Btu.
