Both hydrolysis and thermal expansion involve a change in the structure of a substance. While hydrolysis is a chemical reaction that involves the breaking of bonds by adding water, thermal expansion is a physical process where materials expand or contract in response to changes in temperature.

The increase in volume of a substance due to an increase in temperature is called thermal expansion. This occurs because as the temperature of a substance rises, the particles within it gain energy and move more, causing them to spread out and increase in volume.

Chemical reactions and magnetic fields are not examples of thermal expansion. Thermal expansion specifically refers to the increase in size of a material when heated and the decrease in size when cooled.
Linear expansion and volumetric expansion are the two types of thermal expansion. Linear expansion is the increase in length of a material when heated, while volumetric expansion refers to the increase in volume of a material when heated.
Thermal expansion is the tendency of a material to change in volume, length, or area in response to a change in temperature. The two main types of thermal expansion are linear expansion, where an object grows in length in one dimension, and volumetric expansion, where an object expands in all dimensions.
