Heating Curve


The graph shows the heating curve of element Y.
Describe the graph in terms of state of matter, particle arrangements and changes in energy.

From t0 – t1


1 In liquid state


2 Particles are arranged closed to each other but not closely packed together


3 Particles are not arranged in order


4 Energy increases



From t1 – t2


5 In liquid and gas state


6 Some particles are close to each but some are far apart


7 Particles are not arranged in order


8 Energy remains constant//does not increase



From t2 – t3


9 In gas state


10 particles are far apart from each other


11 Particles are not arranged in order


12 Energy increase
