Practical tools for measured work
Heat capacity calculator
Solve heat, mass, specific heat or temperature change with Q = mcΔT.
Calculate the layout, check the diagram, then print the result for the shop or jobsite.
How it works
Q = mcΔT. Specific heat capacity is per kilogram; total heat capacity is mc. A temperature difference in kelvin has the same numerical value as a Celsius difference. Negative Q and ΔT describe cooling. For 2 kg of water at c = 4186 J/(kg·K), a 10 K change requires 83720 J.
Current-input example
The result above uses these exact values. This snapshot is included when the page is printed so the output can be checked against the original measurements.
- Quantity to calculate
- Heat transferred
- Mass
- 2 kg
- Specific heat capacity
- 4186 J/(kg·K)
- Temperature change
- 10 K
Primary result: Heat transferred: 83720 J.
Before using the result
- Check the selected mode, units and input values before using the result.
- Read the assumptions and rounding rules; compare the worked example with your intended calculation.
- A numerical result does not supply missing context or change the stated limitations.
Limitations
Constant specific heat, no phase change and no heat loss. The example water value is near 15°C and is not constant over every temperature or pressure. Mass and specific heat must be positive.
Frequently asked questions
What should I verify before using this result?
Check the input values, units, dates and assumptions. Compare the method and its stated limits with the source relevant to your task.
Why might the finished result differ?
Results depend on the entered data and the model’s assumptions. Rounding, changing conditions or omitted factors can affect the comparison. Read the limitations before using the result.
