2. How to Use

Using the thermal energy calculator is straightforward:

1. Identify the materials involved in your energy transfer process.
2. Measure the mass of these materials.
3. Determine the specific heat capacity for each material.
4. Measure the temperature change that the materials undergo.
5. Input the gathered data into the calculator.

With just these steps, you can arrive at an accurate calculation of thermal energy.

3. Formula

The formula for calculating thermal energy is:

Q = mcΔT

Where:

• Q = Thermal energy (in Joules)
• m = Mass (in kilograms)
• c = Specific heat capacity (in J/kg°C)
• ΔT = Change in temperature (in °C)

4. Example Calculation

Consider an example where you have 5 kg of water with a specific heat capacity of 4,186 J/kg°C. If the water temperature increases from 20°C to 80°C, how much thermal energy is absorbed?

Using the formula:

Q = mcΔT

Q = 5 kg × 4,186 J/kg°C × (80°C – 20°C)

Q = 5 kg × 4,186 J/kg°C × 60°C = 1,255,800 Joules

Thus, the water absorbs 1,255,800 Joules of thermal energy.

5. Limitations

Despite the thermal energy calculator being a powerful tool, it has its limitations:

• The calculator assumes uniform temperature distribution, which might not always occur in real-life scenarios.
• It does not account for phase changes (like melting or boiling) unless specifically designed to do so.
