I VENTURE to call attention to a simple and effective way of demonstrating the linear expansion of solids when heated, first suggested, I believe, by M. Kapoustine (Journal de Physique, December 1883, ...

Just about every (but not all) solids expand with an increase in temperature. Why? Before going to the answer, let's look at a common model of a solid - the ball and spring model. In this model, solid ...

When things heat up, most solids expand as higher temperatures cause atoms to vibrate more dramatically, necessitating more space. But some solid crystals, like scandium fluoride, shrink when heated — ...

In general, solids and liquids do not burn as a flame—not paper, not even gasoline. What does burn, however, are the vapors that emanate from solids and liquids. With a lighted candle, melted wax ...

In a landmark experiment, scientists have directly measured the temperature of atoms in “warm dense matter” for the first time, overturning four decades of theory and redefining the limits of how hot ...

Gold usually melts at 1,300 kelvins—a temperature hotter than fresh lava from a volcano. But scientists recently shot a nanometers-thick sample of gold with a laser and heated it to an astonishing ...

Scientific American is part of Springer Nature, which owns or has commercial relations with thousands of scientific publications (many of them can be found at www ...

In general, solids and liquids do not burn as a flame—not paper, not even gasoline. What does burn, however, are the vapors that emanate from solids and liquids. With a lighted candle, melted wax ...

MR. MADAN's description of a device for showing that metals and solids expand when exposed to heat is very interesting, especially as such an arrangement, but with important modifications, is capable ...
