Solve for heat, mass, temperature shift, or capacity. Use presets, custom inputs, downloads, and charts. Clean layouts keep every thermal estimate readable on screens.
Enter both temperatures when possible. If not, provide a direct temperature change. Negative heat or negative delta T represents cooling.
| Material | Mass (kg) | Start (°C) | End (°C) | ΔT (°C) | Specific Heat (J/kg·K) | Estimated Heat (kJ) |
|---|---|---|---|---|---|---|
| Water | 2.00 | 20 | 60 | 40 | 4186 | 334.88 |
| Aluminum | 1.50 | 25 | 80 | 55 | 900 | 74.25 |
| Copper | 0.75 | 30 | 110 | 80 | 385 | 23.10 |
| Concrete | 10.00 | 18 | 35 | 17 | 880 | 149.60 |
| Glass | 3.00 | 15 | 65 | 50 | 840 | 126.00 |
Useful heat energy equals mass multiplied by specific heat and temperature change.
Total heat capacity equals total mass multiplied by specific heat.
Rearranged to estimate specific heat from measured energy, mass, and temperature change.
Rearranged to estimate mass when energy, specific heat, and temperature change are known.
Rearranged to estimate temperature change for heating or cooling.
Final temperature follows from the sensible-heat equation when no phase change occurs.
Actual delivered energy rises when heaters or systems are not perfectly efficient.
Heating time is estimated from supplied energy and heater power in watts.
It estimates heat energy, specific heat, mass, temperature change, total heat capacity, or final temperature using standard sensible-heat equations.
Specific heat describes one unit of mass. Heat capacity describes the whole object. Heat capacity equals mass multiplied by specific heat.
Yes. Negative values represent cooling or heat leaving the system. Keep the sign direction physically consistent with your measured temperature change.
No. This model ignores latent heat. Use it only when the material stays in the same phase throughout the temperature range.
Both temperatures are better because they also support the final-temperature chart. Delta T works well when only the measured change is known.
Presets are useful reference values. Real specific heat changes with purity, temperature, moisture, and composition, so lab-grade work may need measured data.
Efficiency helps estimate real input energy. A heater with losses needs more supplied energy than the useful thermal energy stored by the material.
Check units, sign direction, phase changes, and measurement quality. A wrong mass unit or temperature unit often causes the largest errors.
