1. What is the Temperature Change Formula?

The temperature change formula calculates how much a substance's temperature will change when a certain amount of heat energy (BTU) is applied, based on its mass and specific heat capacity.

2. How Does the Calculator Work?

The calculator uses the temperature change formula:

Where:

• \( \Delta T \) — Temperature change (°F)
• \( BTU \) — British Thermal Units
• \( Mass \) — Mass of the substance (lbs)
• \( Specific\ Heat \) — Specific heat capacity (BTU/lb°F)

Explanation: The formula shows that temperature change is directly proportional to the amount of heat added and inversely proportional to both the mass and specific heat of the material.

3. Importance of Temperature Change Calculation

Details: Calculating temperature change is essential in HVAC systems, thermal engineering, cooking, and any application where heat transfer and temperature control are important.

4. Using the Calculator

Tips: Enter BTU value, mass in pounds, and specific heat in BTU/lb°F. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is a BTU?
A: A British Thermal Unit (BTU) is the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit.

Q2: What is specific heat capacity?
A: Specific heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius (or Fahrenheit).

Q3: Why do different materials have different specific heats?
A: Different materials require different amounts of energy to change temperature because of variations in their molecular structure and bonding.

Q4: Can this formula be used for cooling calculations?
A: Yes, the same formula applies for cooling, with the temperature change being negative when heat is removed.

Q5: What are typical specific heat values?
A: Water has a specific heat of 1 BTU/lb°F, while materials like aluminum (0.22), copper (0.09), and air (0.24) have lower values.
