Scientists at the Neverland University claim they have discovered a new substance called 'ironium'. The material shows the following properties near its triple point of 129.023 K and 104.7851 kPa: (a) (b) (dp) (dp) dT)vaporisation d7fusion (dp) d7) sublimation (i) Draw the temperature-pressure phase diagram of pure 'ironium' based on the properties above. Label the axes and regions of stability for the three main phases of 'ironium'. (i) (ii) Add labelled arrows across the phase boundary lines that represent fusion, vaporisation, and sublimation. Define the term triple point in a complete sentence using your own words. (ii) Explain why adding more 'ironium' to a closed system containing only pure 'ironium' will not affect its triple point. (c) Explain what is unusual, but not thermodynamically impossible, about the freezing of 'ironium' using the Clausius-Clapeyron equation. (d) State which property of 'ironium' violates the laws of thermodynamics and explain why.
