👉 Expansivity is a property that describes how an object, such as a material or substance, expands when subjected to temperature changes. It refers to the ability of a material to expand in response to changes in its surrounding environment. In other words, expansivity allows a material to expand without breaking apart under the influence of temperature changes. This property is crucial for many practical applications, including materials that need to be able to withstand high temperatures or those that require flexibility when subjected to temperature fluctuations. For example
