Liquids and Solids Expand Only Slightly When Heated, Whereas Gases

question 413

Multiple Choice

Liquids and solids expand only slightly when heated, whereas gases expand appreciably when heated. If the gas is not free to expand, its pressure rises when heated. Certain substances may melt, burn, boil, or explode, depending on their composition and structure. Thus, the thermal behavior of a substance is closely related to its structure. Raymond A.
