How many triple points are there on the graph
k the following liquids in order of increasing boiling points, from lowest to nest: NH3 / Ar / N2. Explain. ow is the phase diagram of sulphur. At 95.4'C, the densities of rhombic and 1oclinic sulphur are 2.07 g cm³ and 1.96 g cm³, whilst the enthalpy change for th se transition from rhombic to monoclinic sulphur is 0.3 kJ mol". Sulfur 153°C, 1420 atm Liquid 95.4°C 115.21°C 1 atm Monoclinic 444.6°C 115.2°C, 3.2 x 10-5 atm Rhombic 95.3°C, 5.1 x 10-6 atm Gas T ow many triple points are there? Vhat is the most stable form of sulphur under normal conditions? Describe what happens when sulphur at 1 atm is heated from 80°C to 200°C. Determine the volume change AV for the transformation from rhombic to noclinic sulphur. Estimate the pressure at which rhombic and monoclinic sulphur coexist in ilibrium at a temperature of 373 K. slope of the solid-liquid coexistence curve in the water phase diagram is -135 /K. At 1 atm, an 80 kg ice skater manages 2 cm? contact area with the ice (really -p skates). What pressure is exerted on the ice by the skater?
