Heat (q) vs Mass of Solution/Substance

Calorimetry

Formula

q = m × c × ΔT

Where:

  • q = heat absorbed or released (J)
  • m = mass (g)
  • c = specific heat capacity (J/(g·K))
  • ΔT = temperature change (K or °C)
  • Positive q means heat absorbed (endothermic). Negative q means heat released (exothermic).

    Example Calculation

    100 g of water (c = 4.184 J/(g·K)) rises by 5 K.

    1. 01q = m × c × ΔT
    2. 02q = 100 × 4.184 × 5
    3. 03q = 2092 J
    4. 04q = 2.092 kJ
