A liquid can exist only
A
Between triple point and critical temperature
B
At any temperature above the melting point
C
Between melting point and critical temperature
D
Between boiling and melting temperature
Answer
Between melting point and critical temperature
Explanation
Solution
A liquid can exist between boiling point and melting point. These both describe temperature at which phase change occurs in substances. The main difference between boiling point and melting point is that melting point is defined as the temperature at which solid and liquid phases are in equilibrium whereas the boiling point is the temperature at which the vapour pressure of a liquid is equal to external pressure.
