1.	Explanation the phenomenon of thermal expansion
Answer» Thermal expansion is the increase, or decrease, of the size (length, AREA, or volume) of a body due to a change in temperature. Thermal expansion is LARGE for gases, and relatively small, but not negligible, for liquids and solids. ... Thermal stress is created when thermal expansion is constrained.Explanation:Thermal expansion is the tendency of MATTER to change its shape, area, and volume in RESPONSE to a change in temperature. Temperature is a monotonic function of the average molecular kinetic energy of a substance. When a substance is heated, the kinetic energy of its molecules increases
