Volume expansion takes placein liquids and gases. It depends in the change in temperature, fundamental volume, and the kind of substance. When something alters temperature, it increases or decreases ...

The change in temperature of a body causes expansion or contraction of that body. Most of the substances expand on heating and contract on cooling. This is called thermal expansion. It has been ...

Negative thermal expansion (NTE) is fascinating as it involves a material’s volume contraction rather than expansion upon heating. Although NTE lattices typically have highly flexible frameworks, the ...

Most materials expand when they are heated, but some contract instead. A record value of this effect — known as negative thermal expansion — has now been observed in magnetic nanocrystals. Controlling ...
