1. What is the Energy Released Formula?

The energy released formula calculates the thermal energy transferred when a substance undergoes a temperature change. It's based on the principle of heat transfer and specific heat capacity of materials.

2. How Does the Calculator Work?

The calculator uses the energy released formula:

Where:

• \( Q \) — Energy released (Joules)
• \( m \) — Mass of the substance (kg)
• \( c \) — Specific heat capacity (J/kg°C)
• \( \Delta T \) — Temperature change (°C)

Explanation: The formula calculates the amount of thermal energy released or absorbed when a substance changes temperature, based on its mass and specific heat capacity.

3. Importance of Energy Calculation

Details: Calculating energy released is crucial for thermal analysis, engineering design, climate control systems, and understanding heat transfer processes in various applications.

4. Using the Calculator

Tips: Enter mass in kilograms, specific heat in J/kg°C, and temperature change in °C. All values must be valid positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is specific heat capacity?
A: Specific heat capacity is the amount of heat energy required to raise the temperature of 1 kg of a substance by 1°C.

Q2: Can this formula calculate energy absorbed?
A: Yes, the same formula applies. A positive ΔT indicates energy absorbed, while a negative ΔT indicates energy released.

Q3: What are typical specific heat values?
A: Water: 4186 J/kg°C, Aluminum: 900 J/kg°C, Iron: 450 J/kg°C, Copper: 385 J/kg°C.

Q4: Does this work for phase changes?
A: No, this formula only applies to temperature changes without phase transition. Phase changes require latent heat calculations.

Q5: What units should I use?
A: Use kilograms for mass, Joules per kilogram per degree Celsius for specific heat, and degrees Celsius for temperature change.
