Pure anhydrous caffeine is a bitter-tasting, white, odorless powder with a melting point of 235–238 °C. [7] [8] Caffeine is moderately soluble in water at room temperature (2 g/100 mL), but quickly soluble in boiling water (66 g/100 mL). [197] It is also moderately soluble in ethanol (1.5 g/100 mL).

The Gmelin rare earths handbook lists 1522 °C and 1550 °C as two melting points given in the literature, the most recent reference [Handbook on the chemistry and physics of rare earths, vol.12 (1989)] is given with 1529 °C.
For the first time since 2022, a total lunar eclipse will cause the moon to turn red as it passes through the Earth's shadow. Unlike a total solar eclipse that is visible from only a small area ...
Solid carbon dioxide sublimes rapidly along the solid-gas boundary (sublimation point) below the triple point (e.g., at the temperature of −78.5 °C, at atmospheric pressure), whereas its melting into liquid CO 2 can occur along the solid-liquid boundary (melting point) at pressures and temperatures above the triple point (i.e., 5.1 atm, − ...
The two-year starter will be a fascinating draft prospect for NFL teams. Milroe was 205-of-319 passing for 2,844 yards and 16 TDs with 11 interceptions in 2024.
