0 1 A chef wants to melt 0.5kg of chocolate.
0 1 . 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
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
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.
[1 mark]
, 3 of 17
0 1 . 5 Explain what will happen to the mass of the chocolate when it has all melted.
[2 marks]
0 1 . 6 Melting is an example of a physical change.
Explain why melting is a physical change rather than a chemical change.
