Mixture Temperature Calculator (Thermal Equilibrium)

Favorite

Compute the final temperature when two substances reach thermal equilibrium: m₁c₁(T₁−T) = m₂c₂(T−T₂), with the heat exchanged.

Key points

Mixture Temperature Calculator (Thermal Equilibrium): Compute the final temperature when two substances reach thermal equilibrium: m₁c₁(T₁−T) = m₂c₂(T−T₂), with the heat exchanged. Formula: T = (m₁c₁T₁ + m₂c₂T₂) / (m₁c₁ + m₂c₂). Enter parameters on the DD-CAT IDE online tool page to get results instantly, with a calculation-model diagram that updates with the inputs. Thermal equilibrium: heat lost by the hot body equals heat gained by the cold body, i.e. m₁c₁(T₁−T) = m₂c₂(T−T₂). The formula assumes no heat loss, no phase change, and temperature-independent specific heat (ideal model).

Engineering notes

  • Thermal equilibrium: heat lost by the hot body equals heat gained by the cold body, i.e. m₁c₁(T₁−T) = m₂c₂(T−T₂).
  • The formula assumes no heat loss, no phase change, and temperature-independent specific heat (ideal model).
  • If a phase change occurs during mixing (e.g. ice into water), add the latent heat mL.
