work it out
not feeling ready yet? these can help:
heating, cooling, and changes of state
understand conservation of matter using graphs

Explanation:

Answer:

Both conserve mass.
Both are chemical changes.

(Note: The options "Both are caused by cooling" and "Both are changes of state" are incorrect. Log decomposition (rotting) and snails growing shells involve chemical changes (new substances formed or chemical processes in growth), and both follow the law of conservation of mass (mass is conserved in chemical reactions and biological processes).)
