.1
Describe the movement of particles in the chocolate before it is heated.
[1 mark]
0 1 . 2 The chef heats the chocolate over a pan of boiling water. The temperature of the chocolate increases
by 9°C.
The energy transferred to the chocolate was 9450J. Calculate the specific heat capacity
of the chocolate.
Use the correct equation from the Physics Equation Sheet.
[3 marks]
specific heat capacity = J/kg °C
, of 17
0 1 . 3 When the chocolate reaches 30°C, it starts to melt.
The energy required for all of the chocolate to melt can be calculated using the equation:
thermal energy for a change of state = mass × specific latent heat
3
What is the difference between specific heat capacity and specific latent heat?
[2 marks]
0 1 4 . Describe what happens to the temperature of the chocolate as it melts.
