Energy in food (Edexcel GCSE Biology): Flashcards

Process of burning samples to measure energy released

Calorimeter

Joules or calories

Water temperature rise

Dried food that burns easily

Keep away from water to avoid affecting results

$m_{water}\text{(g)} \times \Delta T\text{(°C)} \times 4.2$

$\frac{\text{Energy (J)}}{\text{mass of food (g)}}$

$1\text{cm}^3 = 1\text{g}$

Weigh food and skewer on mounted needle

When food won't catch fire again

Before and after burning food
