Question 3
FA student heats a 0.50 kg block of aluminium with a 60 W immersion heater. The student records the temperature of the block every 60 s. Figure shows the student's results.
Figure: Graph of the temperature of the aluminium block against time
a.[1]
Use Figure to give the temperature of the block at a time of 120 s.
b.[1]
Describe the trend shown by the graph.
c.[3]
Calculate the energy transferred to the block by the heater in the first 300 s.
d.[3]
Use your answer to part c) and Figure to calculate the specific heat capacity of aluminium found by the student.
