Concept explainers
(a)
Interpretation:
The melting point needs to be determined from the given heating curve of chloroform.
Concept Introduction:
The phase transition curve represents the conversion of solid, liquid and gas with increasing the temperature. Here diagonal line shows one phase whereas the horizontal line represents the change in the phase of given substance. As temperature increases solid changes to liquid which further changes to gaseous state by increasing the temperature.
(b)
Interpretation:
The boiling point needs to be determined from the given heating curve of chloroform.
Concept Introduction:
The phase transition curve represents the conversion of solid, liquid and gas with increasing the temperature. Here diagonal line shows one phase whereas the horizontal line represents the change in the phase of given substance. As temperature increases solid changes to liquid which further changes to gaseous state by increasing the temperature.
(c)
Interpretation:
The segments A, B, C, D and E needs to be identified in the given heating curve of chloroform.
Concept Introduction:
The phase transition curve represents the conversion of solid, liquid and gas with increasing the temperature. Here diagonal line shows one phase whereas the horizontal line represents the change in the phase of given substance. As temperature increases solid changes to liquid which further changes to gaseous state by increasing the temperature.
(d)
Interpretation:
The state of chloroform at the given temperature values needs to be determined.
Concept Introduction:
The phase transition curve represents the conversion of solid, liquid and gas with increasing the temperature. Here diagonal line shows one phase whereas the horizontal line represents the change in the phase of given substance. As temperature increases solid changes to liquid which further changes to gaseous state by increasing the temperature.
