Define the term thermal expansion
WebWhat is the definition of thermal expansion? The expansion of substances caused by heating. Why do heated substances expand? Their particles move faster and spread apart. Most ________,_________ and _______ expand when heated. Solids Liquids and Gases. The only substance that expands when cooled and contract when heated. WebLet's explore how to calculate changes in areas of things, when they are heated. By the way changes in area is also called superficial expansion. The good thing is we don't need more physics. We can use whatever we learnt in linear expansion and just apply here. We will eventually define the area expansion coefficient.
