This page provides supplementary chemical data on caffeine. Caffeine ... Melting point: 227 to 228 °C (441 to 442 °F; 500 to 501 K) (anhydrous)
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 ]
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.
Caffeine remains stable up to 200 °C (392 °F) and completely decomposes around 285 °C (545 °F). [190] Given that roasting temperatures do not exceed 200 °C (392 °F) for long and rarely if ever reach 285 °C (545 °F), the caffeine content of a coffee is not likely changed much by the roasting process. [191]
Caffeine does not give you energy, just delays fatigue for a little while longer.” In other words, that 2 p.m. cup of coffee is just delaying the inevitable. At first, caffeine might appear to ...
For example, the melting point of silicon at ambient pressure (0.1 MPa) is 1415 °C, but at pressures in excess of 10 GPa it decreases to 1000 °C. [13] Melting points are often used to characterize organic and inorganic compounds and to ascertain their purity. The melting point of a pure substance is always higher and has a smaller range than ...
Experts say that the window of 9:30 a.m. to 11 a.m. may be the best time to consume coffee.
