Room temperature vs Gallium melting plateau at standard pressure: temperature comparison
Room temperature is 9.765 K lower than the equilibrium melting temperature near 101 kPa of the melting plateau of gallium at standard pressure.
Room temperature describes indoor air conditions generally considered comfortable for people and suitable for ordinary activities.
This is the temperature at which pure gallium changes from solid to liquid under normal atmospheric pressure.

Gallium melting plateau at standard pressure
Equilibrium melting temperature near 101 kPa: 29.76 °C; specified; range 29.75 °C–29.77 °C.
Gallium melts at about 302.9146 K (29.7646 °C) near standard pressure. Purity and pressure affect a realised plateau.
The marked equilibrium melting temperature near 101 kPa is calibrated. Unmeasured illustration details are representative.
