The Heat Transfer Equation (q = mcΔT)
The quantity of heat energy (\(q\)) gained or lost by a substance during a temperature change is directly proportional to its mass and its unique physical molecular structure. This foundational relationship is defined by the classical equation:
Where the individual variables stand for:
- q (Heat Energy Change): Measured in Joules (J). A positive value indicates heat absorbed (endothermic), while a negative value signifies heat released (exothermic).
- m (Mass): The total physical weight of the substance quantified in grams (g).
- c (Specific Heat Capacity): The constant amount of energy required to raise the temperature of exactly one gram of substance by one degree Celsius, measured in J/(g·°C).
- ΔT (Temperature Change): Calculated as Final Temperature minus Initial Temperature (\(T_f - T_i\)).
Calorimetry and Thermal Equilibrium
According to the Law of Conservation of Energy, in an isolated system, heat cannot simply disappear. When a warm object is mixed with a cooler medium, the heat lost by the warmer material must perfectly equal the heat gained by the cooler material:
