Interpretation:
The phase change in mercury sample when temperature is increased from
Concept introduction:
Phase diagram is a graph that represents the solid phase, liquid phase, and gaseous phase of one substance or mixture of substance under different states of temperature and pressure.
The temperature and pressure on a phase diagram at which gas, liquid, and solid phases coexist is called triple point. The temperature and pressure in the phase diagram at which substance is lies between liquid-gas phases is called critical point. The temperature and pressure at which liquid or gas is neither a true liquid nor a true gas is called supercritical point.
Conversion of liquid into gas is called vaporization. Conversion of solid into liquid or vice-versa is called melting or fusion. Conversion of solid into gas is called sublimation.
