(a)
Interpretation: The number of triple points in the given phase diagram of carbon needs to be determined.
Concept Introduction:
The conversion of
The heating -cooling curve is the curve of temperature v/s time that interpret the change in the states of matter with increase in temperature.
Freezing point is the temperature at which the solid state converts to liquid state or vice-versa. Boiling point is the temperature at which the liquid and gas state reach to an equilibrium hence after this temperature, both states must be in equilibrium.
(b)
Interpretation: The phases which coexist at the triple points in the given phase diagram of carbon needs to be determined.
Concept Introduction:
The conversion of solid to liquid and gas involves the change in temperature that can display in heat curve.
The heating -cooling curve is the curve of temperature v/s time that interpret the change in the states of matter with increase in temperature.
Freezing point is the temperature at which the solid state converts to liquid state or vice-versa. Boiling point is the temperature at which the liquid and gas state reach to an equilibrium hence after this temperature, both states must be in equilibrium.
(c)
Interpretation: The change when graphite is subjected at very high pressure at room temperature needs to be explained.
