WebNov 13, 2024 · The entropy of a substance increases with its molecular weight and complexity and with temperature. The entropy also increases as the pressure or concentration becomes smaller. Entropies of gases are much larger than those of condensed phases. WebWhen a material is heated, the kinetic energy of that material increases and its atoms and molecules move about more. This means that each atom will take up more space due to …

WebJun 11, 2024 · Most materials are subject to thermal expansion: a tendency to expand when heated, and to contract when cooled. For this reason, bridges are built with metal expansion joints, so that they can expand and contract without causing faults in the overall structure of the bridge. WebOct 18, 2024 · B.
