Observe the P-T phase diagrams for a given substance A. Then melting point of A(s), boiling point of `A(l)`, critical point of A and triple point of A (at their respective pressure) are respectively-

Options

A. `T_(1),T_(2),T_(3),T_(4)`
B. `T_(4),T_(3),T_(1),T_(2)`
C. `T_(3),T_(4),T_(2),T_(1)`
D. `T_(2),T_(1),T_(3),T_(4)`

Answer

C

Explanation

`mpT_(3) rarr`solid &liquid ,bp`T_(4)rarr`liquid - gas
Critical point `T_(2)`, triple point `T_(1)rarr`solid liquid gas
