Calorimetry (AQA A-Level Chemistry): Flashcards

Experimental technique to measure heat/enthalpy change in reactions

$q$

$q = mc\Delta T$

Mass of substance (in grams)

Specific heat capacity (in $J \, g^{-1} \, K^{-1}$)

Temperature change (in K or °C)

$\text{moles} = \frac{\text{mass}}{M_r}$

$\Delta H = \frac{q}{\text{moles}}$

Polystyrene cup (reduces heat loss)

Graphical extrapolation of temperature data
