Solution

When a substance takes the heat without the change of state, then its volume expands. This is known as thermal expansion.
ie, an object expands and becomes larger due to the change in its temperature. A higher temperature means that the molecules are moving faster on an average, causing them to take up more space. Consequently, objects that are heated up will have an increase in size.
