Q

How many BTUs must be added to one pound of water at 32°F to raise the temperature to 212°F?

🔍 Key Concepts

• The definition of a BTU (British Thermal Unit) and how it relates to heating one pound of water • The specific heat of water in BTU per pound per degree Fahrenheit • How to calculate total heat added using temperature change × specific heat

💭 Think About

• First, figure out how many degrees of temperature change there are between 32°F and 212°F. • Recall how many BTUs are needed to raise 1 lb of water by 1°F. • Multiply the temperature change by the BTU-per-degree value and compare your result to the answer choices.

✅ Before You Answer

• Be sure you are only dealing with sensible heat (no phase change) from 32°F to 212°F. • Confirm that you're using the correct specific heat value for water in BTU/lb·°F. • Double-check your multiplication to ensure the final BTU value matches one of the choices exactly.
