Formula and method
For 2 kilograms, a 10-degree Celsius temperature rise and a hypothetical heat capacity of 100 joules per kilogram-kelvin, the modeled heat transfer is 2,000 joules.
Q = mass×specific heat capacity×temperature change; temperature change = final−initial temperature.

Assumptions and limitations
- Use positive mass and positive specific heat capacity, with a nonzero temperature change and absolute temperatures no lower than zero kelvin. Cooling has negative temperature change and negative heat transfer.
- The material menu contains 62 captured approximate example values plus Custom. Values depend on temperature, pressure, phase and composition; they are not certified measurements of a particular sample.
- This sensible-heat model assumes approximately constant heat capacity and no phase transition. Heat losses, calorimeter heat capacity, reactions and latent heat are excluded.
- Clear the unknown numeric field before solving a supported inverse.
Common questions
What does this scenario assume?
Use positive mass and positive specific heat capacity, with a nonzero temperature change and absolute temperatures no lower than zero kelvin. Cooling has negative temperature change and negative heat transfer.
What does the result leave out?
This sensible-heat model assumes approximately constant heat capacity and no phase transition. Heat losses, calorimeter heat capacity, reactions and latent heat are excluded.
