Ideal Thermal Mixing Calculator

How to use Ideal Thermal Mixing Calculator

For an isolated constant-heat-capacity model, the sum of mc(Tfinal−Tinitial) is zero. Centering on a largest-heat-capacity component avoids extreme-weight cancellation and retains small temperature differences around a large common offset.

1. Enter json material rows [kg, j/(kg k), k].
2. Choose the stated convention and check the units and supported model.
3. Calculate, inspect the result, then copy or download it.

Good to know

• 1–30 JSON rows [mass kg,specific heat J/(kg K),temperature K], positive masses/capacities and nonnegative temperatures. No reactions, phase changes, container heat or material lookup.
• Runs locally. Text/JSON fields are capped at30,000 characters; stricter page-specific and numeric-string limits also apply. Numeric inputs are bounded to magnitude1e15 and nonzero magnitude at least1e-100 unless an exact-string mode states otherwise. Approximate summaries use12 significant digits; CSV numeric cells retain the complete stored value and potentially formula-like string cells gain a protective apostrophe; unsupported, non-finite or detected underflow states return an error.
