, (ii) The energy content of the food is calculated using the equation:
mass of water (g) × temperature rise (°C) × 4.2

energy content (J/g) =
mass of food (g)
The bomb calorimeter was used to find the energy content of a biscuit.
The mass of water was 1 000 g, the temperature rise was 69.4 °C and the mass
of the biscuit was 14.7 g.
Which is the energy content of this biscuit?

A 291 480 J/g
B 19 829 J/g
C 69 400 J/g
D 4 721 J/g
(iii) A different biscuit with the same mass gave a temperature rise of 78.2 °C.
