Pewter has a low melting point, around 170–230 °C (338–446 °F), depending on the exact mixture of metals. [2] [3] The word pewter is possibly a variation of "spelter", a term for zinc alloys (originally a colloquial name for zinc). [4]
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 ]
(For reference, a tall iced coffee at Starbucks, for example, has 135 mg of caffeine, whereas the same size cold brew at the chain contains 155 mg.) That said, when making cold brew at home, you ...
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.
The melting point (or, rarely, liquefaction point) of a substance is the temperature at which it changes state from solid to liquid. At the melting point the solid and liquid phase exist in equilibrium. The melting point of a substance depends on pressure and is usually specified at a standard pressure such as 1 atmosphere or 100 kPa.
"When adding proffee into your diet, be aware of how much coffee you're drinking in a day and aim to limit coffee consumption to 400 milligrams of caffeine per day, which is about four cups ...
