thermal expansion

基本解釋

Experts believe that much of the rise during the 20th century can be attributed to thermal expansion.

Instead of expanding when heated -- as is normally the case -- the material contracts, a phenomenon known as negative thermal expansion.
與正常材料不同的是，儅加熱時，該材料不是膨脹，而是收縮，表現(xiàn)出負的熱膨脹現(xiàn)象。

Warmer temperatures cause water to expand,a phenomenon called thermal expansion, and cause glaciers and polar ice caps to melt.

The other significant factor being the thermal expansion of seawater itself.
