QUESTION 2 Learners conducted an experiment to determine the cooling curve of chlorine. They cooled a cylinder that contained chlorine and recorded the temperature (measured using infrared gun thermometer) over a period of time. The results for the experiment are shown in the graph below. Temperature C 0 -101 -34 26 38 time(minutes) 2.1 Define the term Temperature. 2.2 Use the graph to identify the PHASE/PHASE CHANGE during the following stages. 2.2.1.0 to 9 minutes. 2.2.2 26 to 38 minutes. 2.2.3 beyond 38 minutes. 2.3 Use the graph to identify the following. 2.3.1 Melting point of chlorine. 2.3.2 Boiling point of chlorine. 2.4 Energy is released as chlorine changes phase. Explain how the following properties change as chlorine changes phase between 26 and 38 minutes. 2.4.1 Spaces between the particles. 2.4.2 Movement of the particles.
