Heat Released Calculator – Instantly Find the Energy Released in Chemical or Physical Processes

Mass of Substance * (g)

Enter the mass of the material involved in the process.

Specific Heat Capacity * (J/g°C)

For water, use 4.18 J/g°C. Check your substance's value if unsure.

Initial Temperature * (°C)

Final Temperature * (°C)

For heat released, final temperature should be lower than initial.

Process Type Cooling (Heat Released) Heating (Heat Absorbed)

Choose "Cooling" for exothermic (heat released), "Heating" for endothermic (heat absorbed).

Example Presets:

Cool 250g water from 80°C to 30°C Cool 50g copper from 100°C to 25°C Heat 200g aluminum from 20°C to 90°C Cool 1000g ethanol from 60°C to 20°C Cool 500g iron from 200°C to 50°C

Heat released in a chemical or physical process can be determined using the formula:

Heat Released = Mass × Specific Heat Capacity × Temperature Change

Understanding the Formula

• Mass (in grams): This refers to the quantity of the substance undergoing the process, measured in grams.
• Specific Heat Capacity (in J/g°C): The specific heat capacity represents the amount of heat required to raise the temperature of 1 gram of a substance by 1 degree Celsius.
• Temperature Change (in °C): The change in temperature experienced by the substance during the process.

Using the Calculator

1. Enter the Mass: Input the mass of the substance in grams.
2. Specific Heat Capacity: Provide the specific heat capacity of the substance in Joules per gram per degree Celsius (J/g°C).
3. Temperature Change: Enter the difference in temperature before and after the process in degrees Celsius.

Calculation

Click the ‘Calculate’ button to find the heat released based on the provided values.

The result will display the amount of heat released in Joules.
