Heat (q) vs Mass of Solution/Substance
Fórmula
## 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).
Ejemplo Resuelto
100 g of water (c = 4.184 J/(g·K)) rises by 5 K.
- 01q = m × c × ΔT
- 02q = 100 × 4.184 × 5
- 03q = 2092 J
- 04q = 2.092 kJ
Preguntas Frecuentes
What is calorimetry?
Calorimetry is the measurement of heat changes during chemical or physical processes using a device called a calorimeter.
Why use water in a calorimeter?
Water has a high specific heat (4.184 J/(g·K)), making it good at absorbing heat. Its properties are also well characterized.
What is the difference between q and ΔH?
At constant pressure, q = ΔH. In a bomb calorimeter (constant volume), q = ΔU (internal energy change), which differs slightly from ΔH.
