GATE 2021 ME (ME1) – Question 56

In the vicinity of the triple point, the equation of liquid-vapour boundary in the $P-T$ phase diagram for ammonia is $\ln P=24.38-3063/T$, where $P$ is pressure (in Pa) and $T$ is temperature (in K). Similarly, the solid-vapour boundary is given by $\ln P=27.92-3754/T$. The temperature at the triple point is _____ K (round off to one decimal place).
